Answer 1

Answer:

The correct answer is "Transcription occurs only in prokaryotic cells in the cytosol white splicing occurs only in eukaryotic cell in the nucleus".

Explanation:

Prokaryotic cells and eukaryotic cells could be differentiated by the site at which transcription occurs (the synthesis of mRNA from a DNA template). In prokaryotic cells transcription occurs in the cytosol, while in eukaryotic cells transcription occurs in the nucleus. This is easy to remember since prokaryotic cells do not have a nucleus. Also, splicing occurs only in eukaryotic cells in the nucleus. Splicing is the removal of the non coding regions of mRNA (introns), which happens frequently in eukaryotic cells and in prokaryotic cells is a very rare event.

Answer 2

Answer:

Transcription only occur in eukaryotic cells. Transcription and slicing both occur in the nucleus.

Explanation:

Transcription and splicing only occur in eukaryotic cells. Transcription and splicing both occur in the nucleus. Splicing of exons and intron removal is strictly a eukaryotic phenomenon. Prokaryotic genomes are smaller and do not contain introns. Both of these processes occur in the nucleus.
