Key Concepts

Codon

A codon is a sequence of three nucleotide bases on messenger RNA (mRNA) that specifies a particular amino acid during the process of protein synthesis. Each codon corresponds to one of the twenty amino acids or a stop signal, following the genetic code, and is read in the 5? to 3? direction.

Anticodon

An anticodon is a sequence of three nucleotides found on transfer RNA (tRNA) molecules that is complementary to a specific codon in mRNA. This complementary binding ensures that the correct amino acid is added to the growing polypeptide chain during translation.

Complementary Base Pairing

Complementary base pairing is the principle that adenine (A) pairs with uracil (U) in RNA (and with thymine (T) in DNA), while guanine (G) pairs with cytosine (C). This pairing is critical for the accurate alignment of the anticodon with its corresponding codon during protein synthesis.

Directionality (5? and 3? Ends)

Directionality in RNA refers to the orientation of the nucleotide chain, designated by a 5? (five prime) end and a 3? (three prime) end. In the context of codons and anticodons, understanding this orientation is crucial because the anticodon loop on tRNA is oriented in a direction opposite to that of the codon on mRNA, ensuring proper base pairing during translation.
