DNA Replication

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands

What are the 4 nitrogen bases?

• adenine, thymine, cytoplasm, and guanine
• adenine, thymine cytosine, and guanine
• adenine, thymine, cytosine, and gylcerol
• adenine, thymine, cytosine, and glucose
