Which of the following is not termed as hybridization? a) DNA & cDNA b) DNA & mRNA c) DNA from different species d) DNA from male & female of same species.

DNA from male & female of same species

Explanation:

According to base-pairing rules, adenine (A) always bonds to thymine (T) or Uracil (U), while guanine (G) always bonds to cytosine (C). Nucleic acid hybridization is a process produced by base-pairing complementary between two different DNA (or DNA and RNA) single-stranded molecules to give a hybrid double helix. In consequence, and since hybridization involves base-pairing from different sources, the pairing between DNA strands belonging to male and female of the same species is not considered as a process of hybridization.
