Detailed Solution

In bacteria, Rho( $ρ$ ) factor binds to RNA polymerase to terminate the process of transcription. Some terminations of transcriptions are Rho independent.
(1) Split gene arrangement of cistron is characteristic of eukaryotes and some viruses. Prokaryotes usually do not have split genes.
(2) During capping, 7-methyl guanosine triphosphate is attached to 5’ end of hnRNA. It protects the mRNA from
Nuclease activity.
(4) Coding strand of cistron is not transcribed or copied as RNA. It is template strand of structural gene, which is copied as RNA.
