Question

Chemical mutagens, UV radiation, and ionizing radiation all increase mutation rates, but they have different mechanisms. Which type of mutagen would be best suited for creating large deletions and rearrangements within a genome?

Answer 1

Ionizing radiation would be best suited for creating large deletions and rearrangements within a genome.

Step-by-step explanation:

• In the transcriptionally active genome, the chromosomal rearrangement is enhanced by the ionizing radiation activities.

• By analyzing the inter- and intra-chromosomal events and the actual positions of DNA rearrangement breakpoints, we can say the ionizing radiation mutagen can be suited for creating the deletions within a genome.

• The chromosomal rearrangements are: deficiencies, duplications, inversions, and translocations and deletion involves the removing of a segment in DNA.
