X-rays induce mutagenic changes mainly by _____________.

Question

Verified by Toppr

Answer 1

The first induced mutations were created by treating Drosophila with X-rays. Using this approach Mueller to induce lethal mutations. In addition to X-rays, other types of radiation treatments that have proven useful include gamma rays and fast neutron bombardment. These treatments can induce point mutations (changes in a single nucleotide) or deletions (loss of a chromosomal segment). The deletion leads to chromosomal breakage.
So, the correct option is 'D'.
