DNA Replication by

The "players" involved

Helicase is an enzyme that untwists the double helix. It starts at the origin of replication and creates a fork. Polymerase is an enzyme that builds the new strands of DNA, note: DNA technically only moves in one direction. Ligase helps the process by linking short DNA strands. SSB prevents reannealing, which can be a serious problem. The sliding clam holds the polymerase in place while it is building the new DNA.

These fragments are on the lagging strand and are joined by the ligase enzyme. They are short and are separated by the RNA primers.

Semi Conservative

DNA is semi-conservative meaning that when DNA makes a copy, one half of the old strand is kept in the new strand. This actually reduces the amount of copying errors

3' to 5' directions and how this plays a role in how DNA is replicated

This is the direction in which DNA is read and the leading strand goes this way. This means that DNA is built upwards. It plays a role because DNA polymerase reads the bases on the leading strand. It places the nucleotides in place as the leading strand moves toward the replication fork.

Base pairing Rules

Adenine goes with thymine. Guanine goes with cytosine. Because of this, this lets DNA be put together. This is what forms the double helix. When the replication is done, there is one old and one new strand.
