|The 'tools' needed for translation are ...|
... a single strand of RNA copied from DNA molecule. This is the messenger RNA (mRNA) molecule that carries the codes.|
Ribosomes, which are the sites of assembly of the polypeptide.
Amino acids, all 20 - 22 of which must be present at the same time.
Small highly specific RNA molecules called transfer (tRNA) to which amino acids are covalently bound and which play a part in the decoding of the genetic code.
ATP is required as a source of energy for this highly non spontaneous process.
Various proteins and enzymes; for example the set of enzymes which specifically join the amino acids to the tRNA molecules.
