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

AIPMTAIPMT 2010Molecular Basis of Inheritance

Solution:

Unlike in prokaryotes where transcription and translation take place in the same compartment, in eukaryotes primary transcript is first processed in the nucleus and then transported outside of the nucleus. Since the primary transcripts of the eukaryotes contains both the expressing genes (exons) and non-expressing genes (introns), it undergoes splicing of introns and later capping and tailing at 5'-end and 3'-end respectively.
