Solution


Q.

Identify the correct statement.                                             [2021]
1 Split gene arrangement is characteristic of prokaryotes.  
2 In capping, methyl guanosine triphosphate is added to the 3′ end of hnRNA.  
3 RNA polymerase binds with Rho factor to terminate the process of transcription in bacteria.  
4 The coding strand in a transcription unit is copied to an mRNA.  

Ans.

(3)

Split gene arrangement is a characteristic of eukaryotes. In capping, an unusual nucleotide (methyl guanosine triphosphate) is added to the 5′-end of hnRNA. RNA polymerase binds with termination factor Rho (ρ) to terminate the process of transcription in bacteria. The coding strand does not code for anything.
