Section C (40 marks) Answer ALL questions from this Section 5. You have isolated total RNA from muscle cells and constructeda muscle cDNA library. You wish to study the regulatory region of a muscle-specific cDNA gene (gene M) that you have previously identified. 6 (a) For your study, you need to isolate a genomic clone of gene M. Why isa cDNA clone of gene M not appropriate for your study? (2 marks) (b) Outline the steps you would...

A) repressons B) lactose C) RNA polymerase D) promoters E) enzymes 25) 26) In bacteria, what name is given to a cluster of genes with related functions, along with their control 26) A) exon B) operon C) promoter D) activator E) regulatory gene A mutant bacterial cell has a defective aminoacyl synthetase that attaches a lysine to tRNAs with the anticodon AAA instead...
Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
Select which statement explains the reason why hair does not
normally grow on your muscle cells.
a.
Muscle cells have the gene for keratin, but do not express
it
b.
Muscle cells do not have the gene for keratin and...
