Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Mutations result from errors during replication, mitosis, meiosis, or damage to DNA, which then may trigger error-prone repair or cause an error during replication. Mutations may also result from substitution, insertion or deletion of segments of DNA due to mobile genetic elements.
