what makes up a nucleotide in dna
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 Thymi â¦ ne and Guanine always pairs with Cytosine. Also, in the Rna during DNA transcription, Uracil replaces Thymine and pairs with Adenine instead.
