Translation
Following this, another kind of RNA called tRNA comes to the site of transcription. There are many different varieties of tRNA and each brings binds a different amino acid to it. The topmost part of the tRNA molecule is called the A-Site. This is the location that amino acids bond to the molecule. At the bottom are three nucleotides that from the anticodon. he anticodon consists of the complementary base pairs for a codon on the mRNA molecule. For example, an anticodon of UAG which is complementary to the codon AUG which is the start codon and codes for methionine. Because of this, that tRNA molecule would have a molecule of methionine bound to its A-Site. Also, tRNA has no anticodons that are complementary to the stop codons from mRNA.
The ribosomes have three bonding sites: two for tRNA molecules and one for the mRNA strand. As the ribosome moves along the mRNA molecule, the anticodons of the tRNA molecules bind to the codons in the mRNA and their attached amino acids bond together with peptide bonds to form a polypeptide chain that can eventually fold into proteins. Translation can occur along mRNA molecules at many points simultaneously.
