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.

_______do not appear in mature of processed RNA.

_______do not appear in mature of processed RNA.

Assertion : Monocistronic genes are found in prokaryotes Reason : Polycistronic genes are found in eukaryotes.

Mark the incorrect differences between eukaryotic and prokaryotic transcription. I. In eukaryotes , the genes are split having exons and introns while in prokaryotes it isn't . ii The structural gene which is to be transcribed is generally mono- cistronic in prokaryotes and poly-cistronic in eukaryotes . III . The RAN formed with the help of RNA polymerase in eukaryotes requires future processing to function as m-RNA while in prokaryotes it is directly used as m - RNA. IV. In eukaryotes, RNA polymerase binds to the promoter region while in prokaryotes it binds to the operator region .

Which of the following is correct for mRNA synthesized in leucocytes? (a) Exons and introns do not appear in the mature RNA. (b) Exons appear but introns do not appear in the mature RNA. (c) Introns appear but exons do not appear in the mature RNA. (d) mRNA is not synthesized in leucocytes.

Assertion : Split genes are found in eukaryotes. Reason : Introns or intervening sequences are found in prokaryotes.
