A codon is a set of 3 bases on mRNA that will match a particular tRNA anticodon. Example: AUG
The codon is part of mRNA, but it was copied from the gene which was DNA.

codon is three nuclieotide bases. Nucleotides are 4 types adenine,guanine,cytocine,thymine. These are present in DNA. Adenine,guanine,cytocine,uracil these are present in RNA. Our body contain 20 aminoacids glycine,alanine,valine, phenylalanine,glutamine,glutamicacid,methionine,cystine,asperticacid,tyrosine,tryptophane,proline,isoleucine,leucine,lysine,histidine,argenine,etc.,Three aminoacids are combined to form a one nucleotide. 3 nucleotides are contain (codon) 9 aminoacids. These codons are combined to form a mRNA. these codons are deleberate,nonredundency, nonrepeate. 20 aminoacids form 64 codons. 61 codons are meaningfil codons, other 3 are stopping codons. The first meaningful codon is AUG- it codes methionine.
