Question

What causes mutation? Give example for specific types of mutation.​

Answer 1

Explanation:

A point mutation is a change in a single nucleotide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations,

Answer 2

Mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

Example of Mutation.

. Germline mutations occur in gametes. Somatic mutations occur in other body cells.

. Chromosomal alterations are mutations that change chromosome structure.

. Point mutations change a single nucleotide.

. Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.
