Explain how the structure of DNA is related to its functions (6 marks) - answer-- sugar-phosphate (backbone)/double stranded/helix so provides strength/stability/protects bases/protects hydrogen bonds - long/large molecule so can store lots of information - helix/coiled so compact - base sequence allows information to be stored/ base sequence codes for amino acids/protein - double stranded so replication can occur semi-conservatively/strands can act as templates/complementary base pairing/A-...

Lecture notes from Imperial College London, Medical Biosciences BSc, 2nd year, Cancer Biology (CBIO) module For a cancer to be initiated, certain changes must take place within the genes of a cell. These genes usually control the process of cells growing and reproducing only as required, in an orderly and controlled way (cell proliferation, differentiation, and survival). Studies of tumour viruses revealed that specific genes (called oncogenes) are capable of inducing oncogenic cell changes, ...

Suggest the advantages of the change in blood flow in blood vessels during exercise. [3 marks] - answer--more blood flow to muscles during exercise -supplying more glucose and oxygen/ removing carbon dioxide/ lactic acid/ heat -for high rate of respiration/ to meet increased demand for energy Explain how microorganisms contributed to the increase in temperature during processing of organic waste. [2 marks] - answer-respiration produces heat explain the advantage of showing the data using...

Summary on cancer and how it forms as well as its link to inflammation.

1. Alleles that are neither dominant nor recessive to one another, so both alleles are always expressed in the phenotype. Codominant 2. The inheritance of a single gene Monohybrid inheri- tance 3. Physical, behavioural, biochemical expression of an organisms genotype Phenotype 4. The type of genes an individual has Genotype 5. Alles that is always expressed in the phenotype Dominant 6. Only expressed in the phenotype when homozy- gous Recessive 7. both alleles are...

Revision notes for Cancer Biology covering control of the cell cycle, molecular mechanisms (CDK and Cyclins), cell cycle checkpoints, response to DNA damage. Introduction to oncogenes and tumor suppressors and how various mechanisms link to the hallmarks of cancer.

This document contains a summary of all the course material of theme 1A and B of the subject Mechanisms of Disease 2. DISCLAIMER: this summary consists of practice questions. These questions are not old exam questions, they are purely to see how well you understand the course material. These questions could be used to study, because all lectures, workgroups and small teaching activities are covered.
