HideShow resource information
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
