Biology is taught using a mixture of lectures, skills training (including field courses), classes and tutorials. The lectures lay down the syllabus of each course, and the skills training provides techniques essential for any modern biologist. Our lectures are designed to tell you about the important issues, theories and empirical research in biology, while skills training gives you the tools you need to become a modern biologist. We also use small group teaching for experimental design and quantitative data analysis. Extra reading is encouraged, and this should increase as the course progresses.
Oxford University’s greatest asset is the tutorial system. This system means that you are likely to receive much more personal tuition and greater pastoral support than other universities can offer. The tutorial consists of a one hour meeting, once a week, between the tutor and two or three students. Before the tutorial, your tutor will set you an essay to write and provide you with a reading list. You hand in the essay before the tutorial, which is read and commented on by your tutor, and handed back at the start of the tutorial.
The discussion during the tutorial goes beyond the original topic, giving you a chance to talk about your own ideas and opinions in modern biology. Tutorials are often in blocks of two or more, so that you can cover a topic in depth, and your tutor can get to know you personally. He or she is asked to comment on your performance in tutorials, and these comments are sent to your college at the end of each term.

Starr's Biology Today and Tomorrow
Learning biology through animations, tutorials and quizzes.
View full color, dynamic animations to help you visualize key biological processes. You have the ability to control the animation by turning on or off the narration, playing the animation with or without text, and can start, stop, or rewind the animation to any point you choose.
These 106 in-depth tutorials are designed to illustrate and explain some of the many complex topics in biology. Each tutorial has four elements: an introduction that describes the topic to be illustrated and puts it into a broader context, a detailed animation that clearly illustrates the topic (there are a few tutorials that include simulations or other types of content, rather than animations), a conclusion that summarizes what you should have learned from the animation, and a quiz on the topic covered. The clear presentation of complex topics make these tutorials a powerful learning tool, be sure to work through them in their entirety for the best benefit. New to the Seventh Edition are 20 Key Experiment tutorials that expand upon some of the most important experiments depicted in the book, as well as 10 additional new tutorials. All the animated activities include textbook references, making it easy for you to look up a topic in the text for further explanation. For details on how the tutorials work, click the Help button on the Animation tab of a tutorial.

BioCourse Animation, Movie and PowerPoint
Carnegie Mellon's Office of Technology for Education and Department of Biological Sciences create multimedia materials for teaching and learning Biology. After an analysis of a number of Biology courses was performed to identify when and how shared concepts where taught, a team of biologists, media programmers, and learning experts came together to create animations designed to improve understanding of some of the main concepts taught in Modern Biology and Biochemistry.
Student Center for Biology (The McGraw-Hill Companies)
Welcome to the Student Center for Biology, Seventh Edition. One of the key features of the Student Center are the e-Learning Sessions. The e-Learning Sessions are multimedia enhanced overviews of the chapter concepts. Each chapter's e-Learning Session will contain links to a variety of interactive educational content to help you further expand your understanding of the core chapter concepts: animation, exploration, esp activity, art activity, case study, art review, art quizzes, chapter quiz and more.
Biodiversity (Rediscovering Biology)
Dilution Effect: As suburbs developed in New England, the forest habitat became more patchy, resulting in the disappearance of some species and the proliferation of mice -- which are the reservoir for the Lyme spirochete -- and ticks, which carry the disease to humans. This increased the proportion of infected ticks, and led to an increase in human disease. Mass Extinctions: A graph showing the five major recognized mass extinctions over the last 600 million years. Trilobites went extinct at the end of the Permian era, while dinosaurs were casualties of the most recent mass extinction at the Cretaceous/Tertiary period border. Species Richness vs. Lyme Disease: Ostfeld's study found that as species richness declined, the incidence of Lyme disease increased. Test Strip - Cedar Creek: Each year, David Tilman collects the plant matter from a strip 10 cm by 3 m from each of his experimental plots to examine the effects of species diversity on biomass. Tilman's Experimental Plots: Tilman compares plots with few species (on left) to those with more species (as on the right). He has found that more diverse plots recover from disturbances like drought more quickly than those with fewer species.

Branches of Natural Sciences
Natural science can be broadly divided into two main branches these are life scienceand physical science. Life science is also known as biology,which is the study of living things. Physical science has four subdivisions, which are:
- Astronomy (the study of space)
- Chemistry (the study of substances)
- Earth sciences (the study of our planet)
- Physics(the study of matter and energy).
What is Biology?
The word ‘biology’ comes from the Greek words ‘bios’ (meaning life) and ‘logos’ (meaning study). So biology (AKA life science) is the study of living things and what they do. Biology is a highly diverse subject with many different areas of study. These include morphology(the study of life structures), botany (the study of plants), zoology (the study of animals), genetics (the study of genes), microbiology (the study of microorganisms), and many, many more.
What is Astronomy?
Astronomy is the study of celestial objects and space in general basically, everything beyond Earth’s atmosphere. The word ‘astronomy’ is composed of two Greek words: ‘astron’ (meaning star) and ‘omos’ (meaning arranging). Astronomers study celestial bodies that can be seen from Earth (like the moon, the sun, the stars, and some planets), but also faraway galaxies that can only be observed using powerful telescopes. Astronomy also involves the study of phenomena such as black holes, and theories about dark matter and dark energy.
What is Chemistry?
Chemistry is the study of substances, or matter (i.e. all the ‘stuff’ that makes up the physical world). The purpose of chemistry is to understand the composition, structure, and properties of substances (defined as elements and compounds), and the changes they undergo when reacting with other substances. Chemistry also involves the study of how energy is released or absorbed during those reactions.
What is Earth Science?
Earth science (AKA geoscience) is the study of planet Earth and everything that goes on here. This includes the study of the solid Earth, its oceans, and its atmosphere, as well as the origin and evolution of the planet. There are four major branches of Earth science these are geology, meteorology, astronomy,and oceanography.
Geologyis the study of the origin, history, and structure of the geosphere,i.e. the solid Earth. This includes the study of different rock types, the movement of the Earth’s crust, volcanoes, and earthquakes, among other things. Meteorologyis the study of the Earth’s weather and climate, astronomyis the study of space, and oceanographyis the study of the oceans and their tides, composition, and ecosystems.
What is Physics?
Physics is thought to be one of the oldest academic disciplines on Earth and involves the study of matter, energy, forces, mass and charge. The word ‘physics’ comes from the Ancient Greek word ‘physis,’ meaning nature.Ultimately, physics seeks to make sense of the universe and the laws that govern it.
Physics can be broadly divided into two main branches. These are classical physics(involving theories that predate the 1900s) and modern physics(post-1900 physics that makes use of quantum mechanics and the theory of relativity).
Dev Tutorials are video recordings of developmental biologists describing key concepts in the field. These tutorials are primarily authored by Drs. Michael Barresi and Scott Gilbert who are the co-authors of the 11th Ed. of the textbook “Developmental Biology” by Sinauer Associates. These lessons are to complement the chapters within this text book and serve as a basic coverage of these key concepts.
Purpose: Teachers are encouraged to use these Dev Tutorials to supplement the text and provide an opportunity to offer a “Flipped Classroom” approach to teaching Dev Bio. Students watch these Dev Tutorials before coming to class then, while in class, teachers can incorporate more active learning approaches such as interactive case study problems that are also offered with the 11th Ed.

- It only takes one biological cell to create an organism. A single cell is able to keep itself functional through its ‘miniature machines’ known as organelles. is the process of generating ATP by degrading sugar (glucose). ATP is essential to cell because it is the chief source of chemical energy that fuels many cellular activities. are capable of producing their own sugar (glucose) from inorganic sources and light. They do so through photosynthesis.
- DNA is a double helix structure comprised of nucleotides. A nucleotide, in turn, is made up of a phosphate molecule, a deoxyribose, and a nitrogenous base. The nucleotide sequence in the DNA codes for a particular protein.
- Proteins are synthesized inside the cell. Initially, mRNA transcript is generated. This is then brought to the ribosomes attached to the endoplasmic reticulum for translation. The newly synthesized protein undergoes post-translational modifications in the endoplasmic reticulum and in Golgi apparatus if the protein is to be transported outside the cell.
- Viruses are deemed as obligate parasites as they require a host to become “alive”.
- Organisms, such as animals and humans, have an immune system to combat antigens, especially those causing diseases. Plants may not have the same elaborate specialized cells to hunt down and kill antigens but they have their own strategies to defend themselves. They make use of hydrogen peroxide or chemicals, such as lignin, ethylene, galls, and tannins.

Any technological application which makes use of biological systems or other kind of living organisms for the sake of making products and even modifying the processes is termed as biotechnology. There is widespread application of this field of science as one can find a plethora of new products and processes which are made every day.
In our video lectures, we are going to take a complete detour of this science. Our main focus is the biotech and the pharmaceutical industry however, we will also talk of structural aspects of biomaterials. We believe that in order to make the most of the video tutorials and hone the knowledge in this area, you need to be familiar with what the biomaterials are made of.
There are different analytical technologies which can be used and in these video tutorials, we are going to explain the same to you. You will learn the intricate details of downstream processing along with the techniques of proteomics. Biomathematics and thermodynamics are offshoots of the same and this is why we have lectures devoted to the same. Learn about enzyme science and engineering and explore the details of how biotechnology can help you make some of the smartest products which you can hope for.
Feel free to explore the different lectures and go through them to polish your expertise in the area. Our video lectures will make you an expert in the area of biotechnology and you will be better equipped to understand the dynamics of this field of science
