WebInitiation of replication The replication bubble begins with the enzyme, helicase, breaking the hydrogen bonds between nitrogenous bases of the two parental DNA strands (Fig. 5). In order to prevent the hydrogen bonds from reforming, single-strand DNA-binding proteins (SsBPs) attach to the separated DNA strands (Fig. 6).

Panel B shows electron micrographs of replicating polyoma virus DNA. The viral DNA from polyoma is duplex, circular and relatively small (about 5000 bp), which facilitates resolution of the parts of the replicating molecules.

WebThe diagram below shows a replication bubble with synthesis of the leading and lagging strands on both sides of the bubble. The parental DNA is shown in dark blue, the newly synthesized DNA is light blue, and the RNA primers associated with each strand are red. The origin of replication is indicated by the black dots on the parental strands.
