Transcription and Translation 0.0 / 5 ? BiologyCellular processesA2/A-levelEdexcel Created by: francesca_321Created on: 30-11-15 17:48 Where does Transcription take place? In the nucleus 1 of 17 What is the first step? Genes open up 2 of 17 What breaks between the bases? Hydrogen bonds 3 of 17 What is attracted to the complementary bases? RNA nucleotides 4 of 17 What is formed? Hydrogen bonds 5 of 17 What are RNA nucleotides joined by? the enzyme RNA polymerase 6 of 17 What is therefore made? mRNA 7 of 17 How does it leave the cell> through the nuclear pore 8 of 17 Where does translation take place? In the cytoplasm 9 of 17 Where does the mRNA strand bind to? the cleft in the ribosome 10 of 17 What does tRNA do? It recognises the mRNA codon using its spcific anticodon 11 of 17 What then diffuses into the A site? tRNA 12 of 17 and what? it recognises the mRNA codon there 13 of 17 What forms between the two tRNAs ? a peptide bond 14 of 17 What happens to the tRNA in the P site? It diffuses into the cytoplasm and binds to another specific amino acid 15 of 17 What does tRNA in the P site diffuse too in the cytoplasm? binds to another specific amino acid 16 of 17 What does the ribosome do? moves one codon down the mRNA chain so that the P site is filled with the tRNA from the amino site 17 of 17
