<P> Helicases are a class of enzymes vital to all living organisms . Their main function is to unpackage an organism 's genes . They are motor proteins that move directionally along a nucleic acid phosphodiester backbone , separating two annealed nucleic acid strands ( i.e. , DNA , RNA , or RNA - DNA hybrid ) using energy derived from ATP hydrolysis . There are many helicases resulting from the great variety of processes in which strand separation must be catalyzed . Approximately 1 % of eukaryotic genes code for helicases . The human genome codes for 95 non-redundant helicases : 64 RNA helicases and 31 DNA helicases . Many cellular processes , such as DNA replication , transcription , translation , recombination , DNA repair , and ribosome biogenesis involve the separation of nucleic acid strands that necessitates the use of helicases . </P>
