  2. Bacteria.

  3. Transposons.

  4. All of the above.

Hint:

Biological agents include all molecules that are associated with living organisms.

The correct answer is:

All of the above.


    • Mutagens are factors that cause mutation
    • Mutagens can be classified into: physical, chemical and biological
    • Biological agents include factors which are of biological origin (living organisms)
    • Infectious agents like bacteria, viruses are included under biological mutagens
    • Transposons or jumping genes are sequence of nucleotides that shift its position within a genome
