Potential Questions For The Mocks Already Passed

There is a table, and it asks you to fill it in to show the sequence of amino acids coded for by the original DNA base sequence. There is also a table which pretty much tells you the answers. What is the amino acid sequence? [1] {Ans: Ila, Gly, Val, Ser}Read the passage in revision booklet 7 question 4 on insects. Each phloem-sap-feeding insect receives a few of these bacteria from its parent (lines 16-17). Suggest how this caused a reduction in genetic diversity of the bacteria [2] {Ans: As only a few bacteria are passed on from the parent, so only a few genes are passed on in the bacteria. These genes may not include all the alleles, so the genetic diversity is reduced.}Some enzymes digest protein - they hydrolyse the peptide bonds between amino acids. The extent to which a protein is digested is called the degree of hydrolysis (DH), which can be calculated from the equation: DH= (100 x number of peptide bonds hydrolysed)÷(total number of peptide bonds present) A protein contains 151 amino acids, the total number of peptide bonds in this molecule are therefore 150. A molecule of this protein is digested. The
