A gene X is expressed in brain and leg region in an organism. The gene has two switches: one that activates it in the brain (let's call it brain switch) and another that activates it in the leg (let's call it leg switch). Each is activated by a different activator protein; lets call them brain switch activator and leg switch activator. A mutation (accidental change in DNA sequence) leads to an individual of the species being born with X expression only in the brain. Where might the mutation have occurred?
a) in the promotor of gene X
b) In the leg switch sequence OR in the gene sequence coding for leg switch activator
c) In the gene X
d) Only in the leg switch sequence
Which of the following represents two things that are identical - the sequences of DNA in two sister chromatids before meiosis
Certain restriction enzymes produce cohesive (sticky) ends. this means that they a) make a staggered double-strand cut, leaving the ends with a few nucleotides of single-strand DNA protruding. b)cut in regions of high GC content.
