explain Point mutation.

Answer 1

Point mutation is a type of genetic mutation that occurs when a single nucleotide base in a gene is changed, substituted, or deleted. This type of mutation can have a wide range of effects on the gene, depending on the location of the mutation and the type of nucleotide that is changed. Point mutations can cause a gene to produce a different protein, or they can cause the gene to be non-functional. Point mutations can also cause diseases, such as sickle cell anemia, cystic fibrosis, and Tay-Sachs disease.
