Answer:

number of nitrogen bases

Explanation:

The correct answer would be the number of nitrogen bases.

A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.

Mutation can occur in a variety of ways including:

1. Deletion of nucleotide base sequence in the DNA

2. Addition (insertion) of nucleotide base sequence in the DNA

3. Duplication of nucleotide sequence in the DNA

A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.

Hence, the correct option is number of nitrogen bases.
