Text Solution

Verified by Experts

The correct answer is:

Carcinogen causes tumour. Disjunction of chromosomes takes place in anaphase-I and II when chromosomes move to the opposite poles of the cell. Plectonemic coiling refers to the inter - twining of a double helix DNA molecule in such a way that unwinding of DNA helix molecule is required for its correction. This occurs in mitosis in which sister chromatids are tightly coiled upon each other. In zygotene, homologs align for synapsis.
