The nitrogenous base adenine form hydrogen bonding witha) Thymine b) Cytosine c) Guanine d) None of the above

Question Analysis

In DNA, nitrogenous bases pair with each other through hydrogen bonds, adhering to specific base pairing rules.

Relevant Concepts

1. Base Pairing Rules: Adenine pairs specifically with thymine (in DNA) through two hydrogen bonds.
2. Hydrogen Bonding: Hydrogen bonds are weak interactions that occur between the nitrogenous bases in DNA.

Answer

1. Adenine and Thymine: Adenine (A) pairs with Thymine (T) via two hydrogen bonds.
2. Adenine and Other Bases: Adenine does not form hydrogen bonds with Cytosine (C) or Guanine (G) in DNA, as they pair with each other (C pairs with G).

Final Answer

The correct answer is a) Thymine.
