Answer 1

b. 5' - CAU - 3' is the correct option.

Answer 2

Answer:

B. 5' - CAU - 3'

Explanation:

Unlike the DNA which is a double helical structure the RNA is the single structure where no helix is formed. The bases which are involved in the RNA are Adenine, Guanine, Cytosine, and Uracil instead of thymine.

The main difference is the presence of the Uracil instead of Thymine.
