The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
At the beginning of this reaction, 1 molecule of 'dTTP', 1 molecule of 'dGTP', 1 molecule of 'dATP', 1 molecule of 'RNA primer:origin duplex:DNA polymerase alpha:primase complex', and 1 molecule of 'dCTP' are present. At the end of this reaction, 1 molecule of 'RNA primer-DNA primer:origin duplex' is present.

This reaction takes place in the 'nucleus' and is mediated by the 'DNA-directed DNA polymerase activity' of 'DNA polymerase alpha:primase'.
