RNA and Codons

a macromolecule formed of repeating ribonucleotide units linked by phosphodiester bonds between the 5'-phosphate group of one nucleotide and the 3'-hydroxy group of the next

• LONG NUCLEOTIDE CHAIN

production of a polypeptide at a ribosome from the code on mRNA

• TRANSLATION

• TRANSCRIPTION

the same letter {i.e., base) is not used in the formation of more than one codon.

• The Code is Non-overlapping

• The Code is Degenerate

• The Code is Comma Less

• Code is a Triplet

A review of genetic code dictionary will reveal that most of the amino acids have more than one codon. Out of 61 functional codons, AUG and UGG code to one amino acid each. But remaining 18 amino acids are coded by 59 codons.

• Code is a Triplet

• The Code is Degenerate

• The Code is Non-overlapping

• The Code is Unambiguous
