Question

What is a missense mutation

Answer 1

The right choice is (A) mutation that causes the code for the wrong amino acid.

Step-by-step explanation:

In cell biology during when a missense mutation occurs in a DNA molecule, it varies in one of the RNA codon sequences which are made during transcription. The difference produced in codon will then cause a different amino acid to be inserted into a protein during translation process so we can say that a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid

Answer 2

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

The missense mutation is a type of mutation that affects the amino acids of the organisms. This mutation results in a codon that codes a different amino acid rather than the one that should be coded. Because of this it causes a synthesis of a protein with altered amino acid sequence during translation. This type of mutation is basically a change in one DNA base pair that results in the substitution of one amino acid for another one.
