Question

A frameshift mutation is a dangerous mutation because it...

A. Changes an amino acid.
B. Changes the outcome of all amino acids that genes were originally coded for.
C. Changes all the amino acids originally coded for after the genes that were mutated.
D. Only affects the non-coding regions of DNA.

Answer 1

A frameshift mutation is dangerous because it changes the reading frame of the genetic code and can alter every subsequent codon. This can result in the formation of new proteins with radically different characteristics in the offspring.

Step-by-step explanation:

A frameshift mutation is a dangerous mutation because it changes the reading frame of the genetic code.

This can have drastic consequences as it alters every subsequent codon and may also create stop codons.

Frameshift mutations usually cause multiple amino acid changes, increasing the chances of a new protein being formed with radically different characteristics in the offspring.
