Identify the correct statement.
Options
- AIn capping, methyl guanosine triphosphate is added to the 3 ' end of hnRNA.
- BRNA polymerase binds with Rho factor to terminate the process of transcription in bacteria.
- CThe coding strand in a transcription unit is copied to an mRNA.
- DSplit gene arrangement is characteristic of prokaryotes.
Correct answer
B. RNA polymerase binds with Rho factor to terminate the process of transcription in bacteria.
Step-by-step 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.
