Question

If 14C-labeled uracil is added to the growth medium of cells, what macromolecules will be labeled? If 14C-labeled uracil is added to the growth medium of cells, what macromolecules will be labeled? RNA both DNA and RNA DNA phospholipids proteins

Answer 1

Answer:

RNA

Explanation:

Uracil is one of the pyrimidine bases found in RNA. It is substituted by thymine in DNA.

Hence, if $^{14}C$-labeled uracil base is added to the growth medium of a cell, the uracil will be utilized in the synthesis of RNA and consequently, the synthesized RNA will become $^{14}C$-labeled accordingly.

The correct option is RNA.
