How many nucleotides make up DNA and what are their names?

Answer 1

There are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymine and Guanine always pairs with Cytosine.

Also, in the Rna during DNA transcription, Uracil replaces Thymine and pairs with Adenine instead.

Adenine (A) Thymine (T) Guanine (G) Cytosine (C)

Answer 2

DNA is made up of four types of nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). Each nucleotide consists of a phosphate group, a deoxyribose sugar molecule, and one of these four nitrogenous bases. DNA is a long polymer made up of a sequence of these nucleotides.
