Q165 / 200 · NEET 2021 · Zoology

Identify the correct statement.

  • A
    In capping, methyl guanosine triphosphate is added to the 3' end of hnRNA.
  • Correct answer
    B
    RNA polymerase binds with Rho factor to terminate the process of transcription in bacteria.
  • C
    The coding strand in a transcription unit is copied to an mRNA.
  • D
    Split gene arrangement is characteristic of prokaryotes.

Solution

The termination of transcription is either (a) Rho-dependent or (b) Rho-independent. The rho-protein binds to a specific sequence of DNA and terminates the RNA transcription.
  • The capping is the addition of 7-methyl guanosine (an unusual base) to the 5' end of hnRNA.
  • Split genes are characteristic features of eukaryotes and not prokaryotes.
  • The coding strand is also called the antisense strand and this is not transcribed during the transcription process.

Hence, the correct answer is option: 'B'.
