(a) DNA is located in chromosomes in the form of genes in the cell.

(b) When the DNA already present in the nucleus of a parent cell is copied by making more of DNA by certain biochemical reactions, then slight variations come in the two copies formed. Thus, variations are produced in the offspring's during reproduction which form the basis of evolution.
Example: Offspring's produced by asexual reproduction have slight variations from their parents.
