A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation. It can be a deletion, addition or inversion of a single nucleotide base.
In the following, the mutations that occurred are 1. C and 2. B.
<h3>How the mutation can be explained?</h3>
- <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.
- <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.
Therefore, silent and nonsense mutations are the correct options.

The best way may be is going over the notes on the chapter you were doing. Or going over the chapter once or twice.
The process is called denaturation.
I hope this helped :)
