Use codon tables to translate triplets, explain why the code is triplet, non-overlapping and degenerate, and calculate base requirements for peptide-coding genes.
Stents are used in the treatment of atherosclerosis.
Stents widen the diseased coronary artery so that blood can flow through to the heart muscle.
The diagram shows a stent.
Stents can damage the endothelial cells lining the artery and trigger the formation of a blood clot.
Patients who have a stent fitted are given anticoagulants.
The photograph shows a tropical bont tick.
This bont tick produces a peptide called variegin.
Variegin binds to the active site of thrombin and prevents blood clotting.
Variegin is a peptide consisting of 32 amino acids.
Which is the minimum number of bases in the gene that codes for this peptide?
