Question

Which ofthe following features of genetic code does allow bacteria to produce human insulin by recombinant DNA technology.
(1) Genetic code is not ambiguous
(2) Genetic code is redundant
(3) Genetic code is nearly universal
(4) Genetic code is specific

Answer 1

(4) Genetic code is specific

Answer 2

Answer:

(3) Genetic code is nearly universal

Explanation:

In recombinant DNA technology bacteria is able to produce human insulin because genetic code is nearly universal, that is all contain same nitrogen bases, that is A, G, C, and T

Almost all organism will have amino acids coded by same kind of codons as given in checkerboard because genetic code is nearly universal. Therefore, this property is utilised to produce human insulin using bacteria.

So, the correct answer is 'Genetic code is nearly universal'
