RUTGERS MURPHY BIOCHEM EXAM 3 UPDATED
QUESTIONS WITH CORRECT ANSWERS SOLVED.
A scientist performs an experiment that uses a chemical inhibitor to inhibit a kinase
enzyme in a signaling pathway and this results in a decrease in signaling. If the scientist
wanted to be sure that this kinase was indeed responsible for the decrease in signaling,
which of the following would be the best to use? - CORRECT ANSWER✅✅Use of
siRNA to the kinase mRNA in question.
A western blot is used to detect level of which of the following - CORRECT
ANSWER✅✅protein
