Explain what is meant by the "lagging" strand and why this occurs.

DNA Replication has many key players (enzymes)! These are just a few of the major enzymes. Match the enzymes in DNA replication to their functions in DNA replication.

Primase

Enzyme that unzips the the double-stranded DNA by breaking the hydrogen bonds holding the bases together

Helicase

Enzyme that builds a new DNA molecule by adding complementary strands of DNA to the original, unzipped DNA molecule

Ligase

Enzyme that synthesizes a primer so DNA polymerase knows where to begin working

DNA Polymerase

Enzyme that binds or "glues" fragments of DNA together
