Question

What do a DNA molecule and an RNA molecule have in common?

A. Both are single stranded.
B. Both are double stranded.
C. Both contain the nitrogen base uracil.
D. Both contain the nitrogen base adenine.

Answer 1

I think is D . :) hope is right

Answer 2

D

Step-by-step explanation:

DNA is double stranded and rNA is a single stranded copy of this but T (Thymine) is replaced by U (Uracil). This is done via the biological process of transcription, where a ribosome copies DNA to make this single stranded rNA.
