Answer 1

The two chains of a DNA molecule are bound by their nitrogenous bases to each other by a hydrogen bridge.

This hydrogen bridge is formed between two opposite nitrogenous bases.

There are four nitrogenous bases found in a DNA molecule i.e. Adenine, Guanine, Thymine or Cytosine.

While forming chains adenine is always paired with thymine and guanine is always bridged with cytosine.
