• monosaccharides

All of the following are the parts of a nucleotide, EXCEPT:

• Sugar

• DNA Polymerase

• Primase

• Ligase

Where does DNA replication take place within the cell?

• Nucleus

• Cytoplasm

• Ribosome

• Golgi Body

This enzyme "builds up" the new strands during replication:

• DNA Polymerase

• Ligase

• Primase

• Helicase

The _________ strand is built in fragments known as Okazaki fragments, before ligase comes to bind it all together.

• Leading

• Lagging

• Ligase

• Okazaki
