Mitosis

Multiple Choice

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids

• nucleotides

• fatty acids

• polysaccharides

How Does DNA Replicate?

Step 1: DNA is unzipped by the Helicase

Step 2: Primase give a starting point to begin replication.

Step 3:DNA Plymerase begins pairing the Nucleotides

Step 4: Ligase begins to glue the new DNA together.
