Answer 1

The expected effect of a substitution mutation is that the polypeptide will contain a different amino acid.

Substitution mutations typically involve the replacement of one nucleotide in the DNA sequence with another, which can lead to a change in the amino acid sequence of the resulting polypeptide. This change can potentially alter the function or properties of the protein, depending on the nature and location of the specific amino acid change.
