During your experiment you analysed only a few of the recombinant clones for the presence of thehighly repeated Alu elements. If you wanted to screen for a single-copy gene, you would need to screenall of a much larger genomic library. Assuming, that you already know the amino acid sequence ofunicorn (a species with a similar physiology to humans) insulin, how would you construct a probe whichwould enable you to use nucleic acid hybridisation to screen a unicorn genomic DNA library for theinsulin gene? Hint: you have access to any molecular biology reagents and equipment you might need, such as vectors,enzymes, and DNA sequencers.
