Question
Biology Question on Structure of DNA and RNA
Specific redioactive identification of ribosomal RNA can be achieved by using 14C labelled
A
guanine
B
uracil
C
thyonine
D
cytosine
Answer
uracil
Explanation
Solution
The thymine and the sugar deoxyribose are incorporated into DNA, not in RNA. Adenine, cytosine and guanine are incorporated into both RNA and DNA. Ribose sugar and the base uracil are specific to all the forms of RNA.
