A copper-containing oxygen transport protein from a deep-sea hydrothermal vent tube worm is a quaternary protein consisting of three α\alphaα-polypeptide chains and three β\betaβ-polypeptide chains.
The number of amino acids in each of the β\betaβ-polypeptide chains is 8.235%8.235\%8.235% greater than in each of the α\alphaα-polypeptide chains. Each α\alphaα-polypeptide chain contains 170170170 amino acids.
Calculate the total number of amino acids in this entire quaternary protein. Give your answer to the nearest whole number.
Practise AQA A Level Biology Proteins with exam-style questions for A Level Biology. 22 questions covering General properties of proteins and Many proteins are enzymes, matched to the AQA A Level Biology (7402) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
