Helicase enzyme function in DNA replication is
adding a short segment of RNA to template strand
unwinds the double helix
Forming new strands and removes RNA primer
in chain initiation of the mRNA synthesis
RNA polymerase binds to promoter region of DNA
A portion of DNA template unwinds (opens) at the point of RNA synthesis
Polyadenylation is Addition of a methylated guanine nucleotide at 5’ end of mRNA.
