Question

what type of mutation alters the base, but not the amino acid being coded for?
multiple choice
point
missense
nonsense
silent
back

Explanation:

• Point mutation: A change in a single nucleotide. Can be silent, missense, or nonsense.
• Missense mutation: Changes a codon to code for a different amino acid.
• Nonsense mutation: Changes a codon to a stop codon, prematurely terminating protein synthesis.
• Silent mutation: Alters a base but, due to the degeneracy of the genetic code (multiple codons can code for the same amino acid), the amino acid being coded for remains unchanged.

Answer:

Silent
