Statement A : The primary transcript produced in eukaryotic is translated without undergoing any modification or processing.
Statement B: The hn-RNA in humans has exons and introns.

A

Both the statements A and B are correct

B

Both the statements A and B are incorrect

C

Statement B is correct, and Statament A is Incorrect

D

Statement A is correct, and statement B is incorrect

Text Solution

Verified by Experts

The correct Answer is:
C
The primary transcript contains both introns and exons and are non-functional . Therefore they undergo a process of splicing for removing introns and joining exons in the proper order. It will further undergo post transcriptional modifications I.e capping and tailing After which a fully processed hnRNA is now called mRNA is transported out of the nucleus for translation

Select the correct statements regarding the process of transcription in eukaryotes. (i) The strand of dsDNA which takes part in transcription process is called as coding strand. (ii) The enzyme RNA polymerase can catalyse polymerisation only in one direction i.e. , 5' rarr 3' .

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 .
