2. DNA is in the form of double helix, with very speicfic ways in which the nitrogenous bases pair. A (adenine) always pairs with T (thymine) and C (cytosine) always pairs with G (guanine). mRNA however, does not contain thymine. What base on the mRNA matches up with the adenine on the DNA strand? (The video does not say this but shows it!)(1 point)

Question

Responses

A (adenine)
A (adenine)
C (cytosine)
C (cytosine)
G (guanine)
G (guanine)
U (uracil)

Answer 1

In mRNA, adenine (A) from the DNA pairs with uracil (U) instead of thymine (T). Therefore, the correct response is:

U (uracil).
