8.5- Polypeptide synthesis- Translation 0.0 / 5 ? BiologyDNA, genes and protein synthesisASAQA Created by: Megan2413Created on: 10-04-17 20:34 What is translation? Synthesising a polypeptide from an mRNA molecule 1 of 11 During translation- what attaches to the mRNA strand to the starting codon? A ribosome 2 of 11 What molecule has the anticodon for the starting codon? tRNA molecule 3 of 11 How does the tRNA molecule attach to the mRNA molecule? By complimentary base pairing 4 of 11 What is this tRNA molecule also carrying? The specific amino acid to the anticodon 5 of 11 What does the ribosome do to attach the next tRNA molecule? It moves along the mRNA strand to the next two codons 6 of 11 What bond forms between the first two amino acids as tRNA molecules attach? A peptide bond 7 of 11 How is the peptide bond formed? Using an enzyme and ATP 8 of 11 How many tRNA molecules does a ribosome bring together at one time? 2 9 of 11 Once the ribosome moves past a tRNA molecule, what happens to it? It is released from the mRNA strand 10 of 11 When does this process stop? When the ribosome reaches a stop codon on the mRNA strand 11 of 11
