Definitions:

Anticodon

A sequence of three nucleotides on transfer RNA that is complementary to a codon on messenger RNA, enabling the addition of specific amino acids during protein synthesis.

RNA Polymerases

Enzymes responsible for transcribing RNA from a DNA template, playing a crucial role in the process of gene expression.

Transcription

The process by which the genetic information encoded in DNA is copied into messenger RNA, leading to protein synthesis.

tRNA Triplet

A sequence of three nucleotides in transfer RNA that corresponds to a complementary codon in messenger RNA during protein synthesis.
