Question
Specific radioactive identification of ribosomal RNA can be achieved by using C14 labelled
Guanine
Uracil
thymine
Cytocine
Solution
B.
Uracil
The pyrimidine, thymine and the sugar deoxyribose are incorporated into DNA, not RNA. Adenine, Cytosine and Guanine are incorporated into DNA, not 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.
