Give an account of post transcriptional modifications of a eukaryotic mRNA.

Assertion :- Removal of introns is must for transcription of hnRNA ot mRNA. Reason : In bacteria introns are not present.

Assertion (A) Transcription unit is often monocistronic in eukaryotes and polycistronic in prokaryotes Reason ( R ) Exons do not appear in mature RNA, introns appear is mature RNA.

Assertion : The transcription and traslation can be coupled in bacteria. Reason : In bacteria transcription and translation take place in the same compartment and also the mRNA does not require any processing to become active

Following are the stages in the cellular synthesis of a protein. I. Movement of mRNA from the nucleus to cytoplasm. II. Linking of adjacent amino acid molecules. III. Transcription of mRNA from a DNA template. IV. Formation of the polypeptide chain. V. Attachment of the mRNA strand to a ribosome. In which order do these stages take place?

In eukaryotes, after transcription of mRNA, some of its nucleotides are removed before it is translated into a polypeptide. The nucleotides which are removed from mRNA are called :

To build up food reserves in the cytoplasm, chromosomes become unfolded to start transcription of mRNA and RNA, during which phase of meiosis ?
