DNA Helicase

• Synthesizes (makes) new DNA molecules by adding nucleotides to both leading and lagging strands.

• Joins DNA fragments together in the lagging strand by forming bonds between nucleotides.

• Unwinds & separates DNA helix by breaking Hydrogen bonds between nucleotides. Forms the replication fork.

DNA Polymerase

• Synthesizes (makes) new DNA molecules by adding nucleotides to both leading and lagging strands.

• Joins DNA fragments together in the lagging strand by forming bonds between nucleotides.

• Unwinds & separates DNA helix by breaking Hydrogen bonds between nucleotides. Forms the replication fork.

DNA Ligase

• Synthesizes (makes) new DNA molecules by adding nucleotides to both leading and lagging strands.
