DNA Transcription 0.0 / 5 ? BiologyCellular processes and structureInternational BaccalaureateNone Created by: Annie DaltonCreated on: 04-04-15 18:39 Enzymes involved? RNA polymerase 1 of 12 In what direction does the DNA move? From 5' to 3' 2 of 12 What happens during DNA transcription? a DNA sequence is copied into a complementary RNA sequence 3 of 12 Which strand is transcribed? Anti-sense 4 of 12 What occurs at the Promotor? Initiation of transcription; where RNA polymerase binds and causes the DNA strands to unravel 5 of 12 During transcription, what pairs with adenine? Uracil 6 of 12 What occurs after the DNA strands have unravelled? Free nucleoside triphosphates bind to their complementary base on the anti sense strand which has been unravelled. 7 of 12 What is the role of RNA polymerase? RNA polymerase synthesises an RNA strand in a 5' - 3' direction until it reaches the terminator 8 of 12 What occurs at the Terminator? RNA polymerase and the newly formed RNA strand both detach from the antisense template, and the DNA rewinds 9 of 12 Does this type of transcription occur in prokaryotes or eukaryotes? Prokaryotes 10 of 12 How does the process differ in eukaryotes? Euakaryotic genes may contain non-coding sequences called introns that need to be removed before mature mRNA is formed 11 of 12 What is this process of removing introns called? Splicing 12 of 12
