Question
By which process miss-incorporated base can change into a permanent mutation?
- Replication
- Transcription
- Translation
- Transposition
Hint:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
The correct answer is: Replication
- Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
- All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur.
