Several types of mutation have been taught this lecture. These include (1) promoter mutation, (2) splice site mutation, (3) missense mutation, (4) frameshift mutation, and (5) nonsense mutation. Match the following mutation descriptions with the type(s) of mutations listed above. More than one mutation type might match a description.
a)A mutation that changes several amino acids in a protein and results in a protein that is shorter than the wild-type product.
b)A mutation that produces about 5% of the wild-type amount of an mRNA.
c)A mutation that produces a mutant protein that differs from the wild-type protein at one amino acid position.
d)A mutation that produces protein that is shorter than the wild-type protein but does not have any amino acid changes in the portion produced.
e)A null mutation that does not produce any functional protein product.
Question. Types of mutations:
Answer.
(a). A mutation that changes several amino acids in a protein and results in a protein that is shorter than the wild type product
Answer (a), Non-sense mutation, Missense mutation
