Deletions That Eliminate a Multiple of Three Nucleotides Can

Question

Deletions that eliminate a multiple of three nucleotides can:
A)cause nonsense mutations in an open reading frame.
B)cause frameshift mutations in an open reading frame.
C)delete amino acids in a polypeptide chain.
D)shorten chromosomes from the telomeres inward.
E)cause cancer in a subset of somatic cells.

Accepted Answer

Deletions that eliminate a multiple of three nucleotides within a gene do not cause a frameshift mutation but instead result in the deletion of one or more amino acids in the polypeptide chain, as three nucleotides code for a single amino acid. This type of mutation can alter the protein product but maintains the reading frame of the mRNA.
