Answer:
The correct answer will be nucleus.
Explanation:
Uridine triphosphate is a nucleoside which contains uracil attached to ribose sugar at carbon 1. This uracil containing nucleoside is added in the RNA complementary to adenine while formation.
The RNA is formed in the nucleus of the eukaryotic cell through a process called transcription which produces the mRNA molecule. This mRNA is exported out of the nucleus through nuclear pores to the cytoplasm where it is read by the ribosomes to synthesize the proteins.
Thus, the nucleus is the correct answer.
