Select which example are induced mutations.
a. nitrous acid causes the deamination of adenine to hypoxanthine.
b. transposition causes the formation of deletions.
c. errors in DNA replication cause the formation of point mutations.
d. ionizing radiation causes chromosomal fragmentation

Induced mutation through chemical means can be done by introducing chemical mutagens like nitrous acid. Generally, nitrous acid has the capability to deaminate the nitrogenous bases and also to replace its amino group by a keto group.

So when nitrous acid is added to:

Adenine, it converts to hypoxanthine
Cytosine, it converts to uracil
Guanine, it converts to xanthine

Ionizing radiations using gamma radiations is a type of spontaneous induced mutation which induces genetic variability by causing chromosomal fragmentation and instability.

Select which example are induced mutations. a. nitrous acid causes the deamination of adenine to hypoxanthine. b. transposition causes the formation of deletions. c. errors in DNA replication cause the formation of point mutations. d. ionizing radiation causes chromosomal fragmentation
