7.340 Avoiding Genomic Instability: DNA Replication, the Cell Cycle, and Cancer (MIT)
In this class we will learn about how the process of DNA replication is regulated throughout the cell cycle and what happens when DNA replication goes awry. How does the cell know when and where to begin replicating its DNA? How does a cell prevent its DNA from being replicated more than once? How does damaged DNA cause the cell to arrest DNA replication until that damage has been repaired? And how is the duplication of the genome coordinated with other essential processes? We will examine both

5.3 Purposeful and purposive behaviour

Learning through video clips

The aim of the first three activities was to help you to answer the question ‘What does the term mathematics mean to you?’ Soon you will be asked to view a short video sequence that shows a collection of other people's responses to this question and others that you are trying to answer in this course.

Video clips are used in many OpenLearn units when it is the most suitable way of introducing some aspect of the topic being studied. Here are some of the reasons why video is us

Theologians in Conversation: The 'Five Ways' of St Thomas Aquinas
Thomas Aquinas (1225-74) is famous as the author of five 'proofs for the existence of God' (the 'quinque viae'). But these are not 'knock down' arguments such as one finds in maths or in a law court -- rather ways of coming to realise how different divine existence is from created existence. They are part of Thomas's search for an answer to the question: what is God?

Animal Life Cycles
There are life processes that are so much a part of our experience that it’s easy to take them for granted. Reproduction is one of these processes. It seems quite simple: life cycles result in offspring that resemble their parents. The life cycle patterns of different life forms vary, but the outcome is always the same – the continuity of life is ensured from generation t

4.2.2 Read the whole exam paper through carefully

Students often describe feeling that everyone else starts writing confidently, straight away. Make sure you allow yourself at least 5 minutes to read calmly through the paper. It is tempting to grab at familiar questions, possibly even misreading them and turning them into the questions you want to answer. If you carefully and steadily unpack the questions, you will inevitably make a better selection.

9 Putting it all together

We have covered a wide range of aspects of thinking, particularly those concerned with clear and critical thinking. At this stage, you may find it useful to consider how ideas like these can be put together in ways that will help you when you engage in activities such as reading, writing, speaking and listening. Here is a checklist to use when making judgements about things that you hear, see and experience.

7.4 Proteomics

Traditionally, the study of the biochemistry or structure of a protein necessitated its purification to a high degree. The development of protocols for cloning, manipulation and expression of genes greatly facilitated this kind of study, as will be clear to you from the previous section. In recent years, a number of high-throughput techniques have, to an extent, obviated traditional approaches and permit simultaneous analysis of all the expressed proteins in a cell or organism, known as the <

4.3.4 Wetlands

Wetlands can be used in a similar way to buffer strips as a pollution control mechanism. They often present a relatively cost-effective and practical option for treatment, particularly in environmentally sensitive areas where large waste-water treatment plants are not acceptable. For example, Lake Manzala in Egypt has been suffering from severe pollution problems for several years. This lake is located on the northeastern edge of the Nile Delta, between Damietta and Port Said. Land reclamatio
