what are two types of mutations

Answer 1

There are two types of mutations:

1. Point mutations: These are changes in a single nucleotide base pair in the genetic code. They can be further classified into three categories: silent mutations (where the change does not have any effect on the resulting protein), missense mutations (where the change results in a different amino acid being incorporated into the protein), and nonsense mutations (where the change results in premature termination of the protein synthesis).

2. Chromosomal mutations: These are changes in the structure or number of whole chromosomes. They can be further classified into two categories: numerical abnormalities (changes in the number of chromosomes, such as trisomy) and structural abnormalities (changes in the structure of chromosomes, such as translocations).
