On the mechanism of the modular primer effect.

abstract：:DNA synthesis by phage T4 DNA polymerase is arrested at specific sequences in single-stranded DNA templates. To determine whether or not T4 DNA polymerase accessory proteins 32, 44, 45 and 62 eliminated recognition of these arrest sites, unique primer-templates were constructed in which DNA synthesis began at a DNA pr...
