Question

Mutations caused by mutagenic agents are termed as

• A. Spontaneous mutations
• B. Chromosomal mutations
• C. Induced mutations
• D. None of the above

Answer 1

Answer: (C)

Induced mutations

Mutations can be induced in a variety of ways, such as by exposure to ultraviolet or ionizing radiation or chemical mutagens. Mutations caused by mutagenic agents are termed as induced mutations.

Spontaneous mutations arise from a variety of sources, including errors in DNA replication, spontaneous lesions and transposable genetic elements. Chemical mutation is the changes in the genetic material due to the chemicals and chromosomal mutation is the changes in the number or the structure of chromosomes in the cell.

Thus, the correct answer is option C.
