Question

Describe mutation with an example.

Hint:

Remember: Mutations can be spontaneous or induced; examples include sickle cell anemia and albinism.

Answer 1

Mutation is a sudden heritable change in the DNA sequence of an organism, which can lead to variations. Example: Sickle cell anemia is caused by a point mutation in the hemoglobin gene, where adenine (A) is replaced by thymine (T), resulting in the production of abnormal hemoglobin.
