Question

A genetic mutation that causes a codon that should code for a specific amino acid to be changed into a stop codon results in a shortened protein product and is known as

A.
a frame shift mutation.
B.
a chromosomal mutation.
C.
a nonsense mutation.
D.
a silent mutation.

Answer 1

C

Step-by-step explanation:

A nonsense mutation is a mutation that changes a codon that codes for a specific amino acid into a stop codon. This results in a shortened protein product. The earlier in a nucleotide sequence that this mutation occurs, the shorter the resulting protein will be.

Answer 2

c.nonsense mutation

Step-by-step explanation:

because a nonsense mutation is a mutation in which a sense codon that corresponds to one of the twenty amino acids specified by the genetic code is changed to a chain-terminating codon.
