Section 3: Translation Transcription and Translation Explored 21/22 Q3.31. The diagram below shows DNA and mRNA, and the key elements in initiation and termination for both transcription and translation are highlighted. Can you correctly label the diagram? Drag labels (left) to complete the diagram, and then click Check Answer to get feedback. Incorrectly placed labels will move off the diagram AUG start codon transcription start site ribosome binding site GATATAATIC stop codon DNA terminator Place label here promoter Place label here GCAGGAGGUC GAUAAAA GGAUGCA mRNA Reset Q3.32. The first step in gene expression is transcription. Where does transcription start, and what signals it to end? Use the dropdowns below to complete your answer and is signaled to end by the It is performed by a ribosome promoter Transcription starts at the Reset QQ NOTES QUESTIONS
Q5.9. Suppose a drug blocked the entry of tRNA molecules into the ribosome. What effect would this drug have on gene expression? There would be no effect, because tRNA is not part of the product of gene expression (ie, is not a polypeptide) Transcription initiation would be blocked, so RNA polymerase would never synthesize RNA O Translation elongation would be blocked, so the cell would be unable to synthesize polypeptides Translation termination would be blocked, so the ribosome would remain attached to the polypeptide Submit
