Document Summary

The information contained in our genome is encoded in our genes. This genetic information is transcribed from the sequences of nucleotides along strands of dna into rna. It is then in the process of translation that cellular components are able to read the genetic message in the messenger rna sequence, and translate this message into the specific primary amino acid sequence of a protein. During the process of translation, transfer rna plays a critical role in enabling the translation of the information in the mrna genetic message to a polypeptide. This occurs because trna molecules are able to transfer amino acids, from a pool of cytoplasmically situated amino acids, to a growing polypeptide strand in a ribosome. This is accomplished in a remarkably specific manner since each type of trna molecule is not identical, and as a result can translate a specific mrna codon into a specific amino acid.
