Translation: mature mRNA is translated to protein in the cytoplasm - translation occurs at the ribosomes - many ribosomes may synthesize protein from the same mRNA molecule at the same time (polyribosomes) - tRNA molecules carry amino acids to the ribosome during translation (a tRNA for each amino acid) - ribosome subunits associate immediately prior to translation, and dissociate following translation - ribosomes bind mRNA at the 5’ cap, assisted by rRNA components, and begin translation, usually, at the first AUG ( start ) codon - the initiator (AUG/methionine) binds to the P site to begin translation… all following tRNAs bind to the A site, and transfer their amino acids to the growing polypeptide at the P site - one of 3 stop codons (UAA, UAG, UGA) signals the ribosome to stop translation of the mRNA… following translation, a release factor cleaves the complete polypeptide from the last tRNA and the ribosome, and the polypeptide leaves the ribosome Cell Division: - cell division involves nuclear division and
