MCQ
Gene mutation is caused:
- ADue to reproduction
- BDue to changes in the sequence of nitrogen bases
- CDue to linkage
- DDue to changes in the size of DNA
✓
Answer
- Due to changes in the sequence of nitrogen bases
Explanation:
A gene mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size. They can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. Gene mutation does not occur due to reproduction, linkage or changes in the size of the DNA.
