1 Answer

Answer :

Each DNA molecule is made of thousands of small units called nucleotides. There are four types of nucleotides in DNA.

I. Adenine (A) nucleotides

II. Thymine (T) nucleotides

III. Cytosine (C) nucleotides

IV. Guanine (G) nucleotides

According to them, DNA molecule consists of two stands formed of nucleotides. These two are linked with each other by cross bands like a ladder.
