Codons and Anticodons
Within a strand of messenger RNA there are triplets of nitrogen bases that code for amino acids. These sets of triplets are called codons.
For example, if there is a strand of RNA that has the nitrogen bases U U A C G C A G U, U U A would be a codon, C G C would be a codon, and A G U would be a codon.
Anticodons are the complimentary pairs located on one end of transfer RNA.
Example:
Codons of mRNA: U U A C G C A G U
Anticodons of tRNA: A A U G C G U C A

Anticodons are the complimentary pairs located on one end of transfer RNA.

Anticodons of tRNA: A A U G C G U C A

Codon Chart
Codon charts are used to find the Amino Acid that corresponds to DNA and RNA to produce a chain of amino acids called a polypeptide, or protein.
To use a codon chart you need to know the codons. First, you go to the left side of the chart and find the first letter/ nitrogen base of the codon. You then go to the top of the chart and find the second letter/ nitrogen base of the codon, and then you go to the right and find the last letter/ nitrogen base of the codon that is also in the same row as the first letter of the codon. After that you go to the poitn on the chart where all of the letters of the codon come together and you have the amino acid that corresponds to that specific codon.
Example:
Codons: U U A C G C A G U
Amino Acids: Leu Arg Ser (Information found in class notes)
