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
