Final answer:
A mature mRNA molecule is deposited in the cytoplasm of a eukaryotic cell after being transcribed.
Step-by-step explanation:
After being transcribed, a mature mRNA molecule is deposited in the cytoplasm of a eukaryotic cell. It is transported out of the nucleus and into the cytoplasm through nuclear pores. Once in the cytoplasm, the mature mRNA can be translated by ribosomes to synthesize proteins.
