DNAmutaatio

DNAmutaatio is a change in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations can result from errors in DNA replication or repair, or from external factors such as radiation or chemical mutagens. Mutations can occur in somatic cells, which are the cells of the body, or in germline cells, which are the cells that give rise to sperm and eggs. Mutations in somatic cells are not inherited by offspring, while mutations in germline cells can be passed on to future generations.

The effects of DNAmutaatio can vary widely. Some mutations have no observable effect, while others can cause disease or other changes in the organism. For example, mutations in genes that control cell growth can lead to cancer. Mutations in genes that are essential for survival can be lethal.

DNAmutaatio is a natural process that occurs in all organisms. It is a source of genetic variation, which is essential for evolution. However, mutations can also be harmful, and it is important to protect ourselves from mutagens.
