Question

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

Answer:

D

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.

Answer 2
