The reading of a codon can vary due to insertions but not due to deletions. The organism can benefit from mutations.
Environmental factors including UV light (sunlight), nuclear radiation, or specific chemicals can result in mutations. When a cell duplicates their DNA during replication is order to prepare for cell division, mutations can also take place. Environmental organism known as mutagens are what trigger mutations. The reading of a codon can vary due to insertions but not due to deletions. The organism can benefit from mutations.Mutations may occur naturally spontaneously. Errors with DNA replication during cellular division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to children, but germline mutations (which happen in eggs and sperm) may.
