Question

In eukaryotes,precursor mRNA molecules are processed in the
A)ribosomes.
B)nucleus.
C)mitochondria.
D)cytoplasm.
E)nucleolus.

Accepted Answer

Precursor mRNA molecules undergo processing in the nucleus, which includes capping, splicing, and tailing, before being transported to the cytoplasm for translation in the ribosomes. Mitochondria do have their own genome and transcription machinery but do not process precursor mRNA molecules in eukaryotes. The nucleolus plays a role in the synthesis of ribosomal RNA but not in the processing of mRNA.
