WebORF59 of Kaposi's sarcoma-associated herpesvirus (KSHV) plays an essential role in viral lytic replication by providing DNA processivity activity to the viral DNA polymerase (ORF9). ORF59 forms a homodimer in the cytoplasm and binds and translocates ORF9 into the nucleus, where it secures ORF9 to the origin of lytic DNA replication (oriLyt) in order to … WebThe other strand (termed the lagging strand) cannot be made in this continuous way by DNA polymerase, because it runs in the opposite direction. DNA polymerase can therefore only … hotels with entertainment in hereford
