Question

which of the following is not a mutagen​

Answer 1

Answer:

1) Gamma rays are a high-energy kind of radiation that cause mutation.

2) Nitrous acid (HNO2) is a mutagen (a compound that causes mutations). It is thought to operate by changing the structure of some bases in DNA. For example, it is capable of converting adenine to hypoxanthine.

3) Hydroxylamine is a mutagen that adds a hydroxyl group to cytosine residues. Hydroxylated cytosine can pair with adenine, and so if the hydroxylated base is not correctly repaired before the next round of DNA replication, then the result can be a permanent change in the DNA sequence (i.e. a mutation).

So, the correct answer is 'Acetic acid'.
