Split gene arrangement is characteristic of eukaryotes. In capping, 5-methyl guanosine triphosphate is added at 5' end of hnRNA. At 3' end poly-A tail is added. The non coding or template strand is copied to an mRNA. RNA polymerase associate with $\rho$ factor (Rho factor) and it alters the specificity of the RNA polymerase to terminate the processes.
