The correct answer is:
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together.
Adenine base pairs with thymine with hydrogen bonds and cytosine base pairs with guanine with hydrogen bonds.
As we know that in DNA molecule , adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G).
