Mutation is the source of differences in the dna code.
What is Mutation?
- A mutation is a permanent change in the DNA sequence of an organism.Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
- Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
- Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.
