Mutations can be induced with
A
Gamma radiations
B
Infra Red radiations
C
IAA
D
Ethylene
Detailed Solution
Agents that induce mutations are called mutagens; they change the base sequence or structure of DNA.
High-energy ionising radiations such as gamma rays and X-rays (and non-ionising UV rays) are physical mutagens that damage DNA and cause breaks in chromosomes.
Gamma radiations are used in mutation breeding of crops, e.g., to obtain disease-resistant mung bean.
Infra-red radiation has too little energy to alter DNA; it only produces heat.
IAA (an auxin) and ethylene are plant growth regulators, not mutagens.
Hence mutations can be induced with gamma radiations.
