Q
What is a mutation in an organism?
A
A mutation is a heritable change in the dna of an organism. During Dna replication occasional mistakes can be made in the base sequence during the copying process which can change the amino acids coded for by the sequence of bases. This changed the protein and can lead to changes in the function of an organism.
