C4. Amino Acids and Proteins Amino acids are organic compounds that contain amine and carboxyl functional groups, along with a side chain specific to each amino acid. Clearly and concisely explain the process of dipeptide formation. [10 Marks) C5. Nucleic Acids Humans have two types of nucleic acids in their bodies: DNA and RNA. These molecules contain the set of instructions for our cells: they determine who and what we are. Compare and contrast DNA and RNA. [10 Marks] C6....

What are SOS gene products? How are they induced? A. SOS proteins (RecA, SSB, uvrABC, etc); nicked DNA binds to the Lac repressor, causing its release and degradation, thereby triggering expression of the SOS genes B. SOS proteins are the heat-shock proteins; the “chi” sequence binds to some transcription factors inducing expression of these genes C. SOS proteins are only transcription factors that activate other genes; DNA damage causes induction of these transcription factors through single-stranded DNA binding proteins D....

Sequence Comparisons Proteins called molecular chaperones (described in Chapter 4) assist in the process of protein folding. One class of chaperone found in organisms from bacteria to mammals is heat shock protein 90 (Hsp90). All Hsp90 chaperones contain a 10 amino acid "signature sequence," which allows for ready identification of these proteins in sequence databases. Two representations of this signature sequence are shown below. (a) In this sequence, which amino acid residues are invariant (conserved across all species)? (b) At...

The specific catalytic activity of the telomerase enzymes is best described as: a. Adding extra nucleotides to the 3' DNA overhang at the ends of each chromosome b. Adding extra nucleotides to both strands of DNA at the ends of chromosomes c. Removing 'junk' DNA from the ends of chromosomes d. Generating a new primer sequence on the very tip of the lagging strand after DNA replication e. Coordinating the binding of special telomere cap proteins that protect the ends...
