The correct option is C Both A and B
Mutations can be induced by several methods. The three
general approaches used to generate mutations are radiation, chemical and
transposon insertion.
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).
Chemical mutagens work mostly by inducing point mutations.
Point mutations occur when a single base pair of a gene is changed. These
changes are classified as transitions or transversions. Two major classes of
chemical mutagens are routinely used. These are alkylating agents (such as
ethyl methane sulphonate (EMS), ethyl ethane sulphonate (EES)) and base analogs
(5-bromouracil and 2-aminopurine).
Therefore, the correct answer is option C.
