Explanation / Answer

35)

E is the correct answer, all the statmensta are correct. Electrophoresis is used to separate proteins, dna and Rna respectively as part of Western, southern and northern blotting.

36) all are true about the crispr --cas 9

37) answer is A, the complementary rules are A to U, T to A, G to C, and C to G

38) answer is A, we first digest it with restriction enzymes and then carry out electrophoresis
