Answer:

RNA

Explanation:

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

Hence, if [tex]^{14}C[/tex]-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 [tex]^{14}C[/tex]-labeled accordingly.

The correct option is RNA.
