Elongation

Elongation is the process by which nucleotides are sequentially added to a strand of RNA during transcription of a DNA molecule. This process is mediated by elongation factors. For example, EF-Tu aids the correct pairing of mRNA and tRNA in protein synthesis using GTP as its energy carrier.
