The answer is the second one. Mutation is the changing of the structure of a quality, bringing about a variation shape that might be transmitted to ensuing eras, brought on by the modification of single base units in DNA, or the erasure, addition, or revision of bigger areas of qualities or chromosomes.
Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.
