Are the Changes in Dna Sequence Always Accidental

DNA is constantly subject to mutations, accidental changes in its code. Mutations can lead to missing or malformed proteins, and that can lead to disease. We all start out our lives with some mutations. These mutations inherited from your parents are called germ-line mutations.

What are accidental changes in a genomic sequence of DNA?

7.12C: Mutation. Mutations are accidental changes in a genomic sequence of DNA; this includes the DNA sequence of a cell’s genome or the DNA or RNA sequence.

Do DNA mutations always alter DNA sequence?

While mutations always change the DNA sequence, they do not always cause a change in the resulting protein or an obvious effect on the organism. This can occur because most amino acids can be coded by two or more different codons.
