Primase acts as a molecular brake
Forked DNA molecules (see Supplementary Information for DNA substrate preparation) are attached by one end to the glass surface of a flow cell and by the other end to a bead (see ref. 14 and Supplementary Information). To prevent nonspecific interactions between the beads and the surface, we … See more T7 gp4 with and without the ZBD, and T7 gp5–trx were purified as previously described10,30.
