DNA Replication

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 three components of a nucleotide?

• sugar, hydrogen, nitrogen base
• sugar, oxygen, nitrogen base
• sugar, phosphate, nitrogen base
• sugar, phosphate, protein

The enzyme that unzips the DNA to prepare for replication ("The Unzipper") 

• helicase
• replicase
• polymerase
• synthase

The enzyme that comes first temporarily gets the single strand ready to add new nucleotides is called "The Initializer" or 

• Helicase
• Primase
• Polymerase
• Nuclease

Small segments of DNA made on the lagging strand are called:

• Okazaki Fragments
• ERVs
• Transposable Elements
• Telomeres
