triplet codons of nucleic bases - adenine, uracil, guanine and cytosine. these form amino acids

Nucleotides, of which there are four of them, each containing:
1. a phosphate sugar
2. ribose sugar
3. and either adenine, cytosine, guanine or uracil as a base.
There is no one nucleotide that makes up RNA. It's always a mixture.
Sweetndangry's answer appears to be the best so far, however he/she should have put uracil, not thymine. It's DNA that contains thymine.

RNA is a nucleic acid made up of three nucleotides:
1.pentose sugar-ribose(always say ribose pentose sugar)
2.phosphate
3.organic base-2 types:1. purine which consists of adenine and
guanine.
2. pyrimidine which consists of thymine
and cytosine.

then click on higher education and onto As biology if you need further help with anything.
good luck.

The answer that you're probably looking for is a base, or nucleotide. ACGU in RNA, ACGT in DNA
