What is a missense mutation? a. a mutation that causes the code for the wrong amino acid b. a mutation that causes a person to have an extra chromosome c. a mutation that affects an entire chromosome d. a mutation that adds several extra bases to a gene

The correct answer is a mutation that causes the code for the wrong amino acid.

A missense mutation in genetics refers to a point mutation in which a change in a single nucleotide leads to a codon that code for a distinct amino acid. It is a kind of nonsynonymous substitution.

A missense mutation takes place when one nucleotide of DNA is modified so that a distinct amino acid is presented into a protein. A missense mutation refers to a mutation in which one molecule of DNA is switched out with another in a manner that modifies the specific amino acid.
