Question 4: Explain how a deletion mutation leading to a modification of the 3' untranslated region (UTR) on the CACNA1S mRNA could lead to hypokalemic periodic paralysis without changing the structure of the polypeptide formed? (Note this is not the known cause of hypoKPP, but it makes a good question)

Question 1 options: The specificity pocket of the serine protease chymotrypsin, which interacts with Tyr and Phe-containing peptide sequences, contains a Ser residue. A research group is trying to modify chymotrypsin such that it has a low KM with Trp-containing peptides. Enter the name or abbreviation of an amino acid that the Ser could be mutated to that would likely have the desired effect. (Hint: look at the diagrams of the specificity pockets shown in the course slides, and consider how the Ser would need to change to account for the difference between Tyr/Phe and Trp.)

question 26 What is true for CpG Islands: stretches of a few hundred base pairs of DNA where cytosines are unmethylated are not associated with genes are not found around the promoters are associated with silenced genes
QUESTION 48 Identify the best match between the mutation description and term. a. Synonymous mutation: has the potential to cause large changes in transcription and subsequence amino acid sequence due to reading frameshifts b. Nonsense mutation: causes a drastic change in phenotype because the change causes a premature stop in the amino acid sequence c. Indel: a change in the DNA that changes the codon code from one amino acid to another amino acid d. Missense mutation: results in a change in single nucleotide from a purine to another purine or a pyrimidine to another pyrimidine but does not change the amino acid sequence
Which of the following statement about mRNA is TRUE? Question 12 options: mRNA splicing is a conserved process in both prokaryotes and eukaryotes. Post-transcriptional regulation of gene expression may occur outside of the nucleus in eukaryotes. In eukaryotes, mRNA maturation requires 5'-capping, splicing and the addition of poly A tails. mRNA is transported out of the nucleus for translation in eukarytotes.
