In eukaryotic cell transcription, RNA splicing and RNA capping take place inside the

  • ribosomes

  • nucleus

  • dictyosomes

  • ER

Solution

A.

ribosomes

Transcripiton involves the transfer of genetic information from DNA to functional mRNA. In eukaryotes, the modification of newly formed primary mRNA transcripts (pre- m-RNA) to produce functional mRNA is called RNA processing or post-transcriptional modification. it occurs in the nucleus and involves gene-splicing (i.e removal of introns from primary transcript and splicing together of exons) and capping involves the formation of a cap at 5' end by condensation of guanylate residues. The fully processes mRNA molecules are exported from the nucleus to the ribosomes for translation in the cytoplasm.
