What is a mutation in genetics?
Quick Answer
A mutation is a change in the DNA sequence. Mutations can be harmless, harmful or sometimes beneficial.
The Full Story
Mutations are alterations in genetic material caused by copying errors, radiation, chemicals or other processes. They can involve a single DNA letter, a stretch of DNA or even whole chromosomes. Some mutations have no effect, while others change protein function or gene regulation and can cause disease. Mutations are also the raw material of evolution, creating genetic variation in populations.
Key Facts
1.Mutations are changes in DNA sequence
2.They can be inherited or acquired
3.Some mutations drive evolution and disease
