What is meant by the term proteome?
In recombinant DNA technology, a target gene of interest is inserted into a plasmid vector. Describe the roles of two key enzymes used to insert a DNA fragment into a plasmid.
Scientists have produced transgenic crop plants that produce antisense RNA (single-stranded RNA complementary to target mRNA) to silence a gene responsible for producing a major allergen protein. Suggest how this single-stranded antisense RNA prevents the translation of the allergen protein.
Practise AQA A Level Biology Gene technologies allow the study and alteration of gene function allowing a better understanding of organism function and the design of new industrial and medical processes (A-level only) with exam-style questions for A Level Biology. 9 questions covering Recombinant DNA technology (A-level only), Differences in DNA between individuals of the same species can be exploited for identification and diagnosis of heritable conditions (A-level only), and Genetic fingerprinting (A-level only), 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.
