When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed.

The statement is true.

Explanation:

Mutation can be defined as any permanent alteration in the DNA base sequence of the genome of an organism, that is, a mutation is any change in the nucleotide sequence of the. DNA. This, in turn, can be of two types: By substitution of bases: alterations in the nucleotide sequence of a gene and two classes are known: transitions or transversions, and by loss or insertion of nucleotides: these are modifications where it can be losing or adding a nitrogenous base, which is important for encoding a specific protein and therefore changes the message of the genetic material.
