• Split gene arrangement is characterstic 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 accociate with ρ factor (Rho factor) and it alters the specificity of the RNA polymerase to terminate the processes.
