DNA polymerase a is unusual because it has the ability to initiate a new strand. It is used to initiate both the leading and lagging strands. 

The enzyme exists as a complex consisting of a 180-kD catalytic (DNA polymerase) subunit, which is associated with three other subunits: the B subunit that appears necessary for assembly, and two small subunits that provide the primase (RNA polymerase) activity.  It has dual capacity to prime and extend chains, this complex is often called pol a/primase.

C8 having two peptide chains: C8β and C8αϒ. Binding of C8β with C5b67 complex causes conformational change in the C8 dimer such that hydrophobic domain of C8αϒ can insert into the interior of the phospholipid membrane.

Dissociation of cytosolic complex leads to the stabilization of the full-length Ci, which moves into the

nucleus, displaces the repressor Ci75 from the promoter of target genes, and induces expression of target genes.
