Explain what is meant by the concept of "central dogma of molecular biology". Name the main processes involved in this dogma and highlight the roles of the different types of RNA molecules involved in them. Point mutations in multiple tumor suppressor proteins have been linked to cancer. For example changes in the gene for adenomatous-polyposis-coli protein (APC gene) may result in colorectal cancer. Consider the following DNA sense strand. 3'-TAC CGG TTG TGA AGC TGA ATC-5' (i) (ii) (iii) (iv) Derive the mRNA molecule from the given DNA strand sequence above, paying attention to the polarity of the molecule. Write down the polypeptide chain sequence arising from the mRNA molecule of the question above, using the table of the genetic code (Table Q1 overleaf) and indicate the C- and the N-terminus of the peptide chain. Point mutations of a cytosine (C) often lead to the dysfunction of the APC protein. Write down all possible polypeptide chains that can result from all possible DNA mutations of cytosines, disregarding a mutation in the MET/START and STOP codons. Specify which of the point mutations identified in (d) are redundant?
