Mutation and DNA

Mutation and DNA. Mutation = change(s) in the nucleotide/base sequence of DNA; may occur due to errors in DNA replication or due to the impacts of chemicals or radiation to the DNA molecule Mutation may result in coding sequences for new amino acids in proteins or not!.

Human Heredity

Human Heredity. How does a mutation occur? A chromosome or specific gene is damaged. If a mutation occurs in one of the gamete cells it’s called a germ cell mutation . If a mutation takes place in a 2N cell it’s called a somatic mutation .
