Give scientific reasons : Transcription and translation could be coupled in prokaryotic cell but not in eukaryotic cell.

Option A

Option B

Option C

Option D

Solution

In prokaryotes the $mRNA$ synthesised does not require any processing to become active and both transcription and translation occurs in the same cytosol but in eukaryotes, primary transcript contains both exon and intron and is subjected to a process called splicing where introns are removed and exons are joined in a definite order to form $mRNA.$
