NGSS.HS-LS1-1

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

• amino acids
• nucleotides
• fatty acids
• polysaccharides

The enzyme that unwinds 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

order of replication

• 3, 4, 2, 1
• 3, 1, 4, 2
• 2, 1, 4, 3
• 3, 4, 1, 2

In what phase of the cell cycle does DNA replication take place?

• Prophase

• Interphase

• Metaphase

• All phases

Which enzyme is responsible for adding nucleotides?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

The process of DNA replication is called semi conservative because it results in

• none of these
• Two DNA molecules.  One original molecule and one with two new strands
• two exact copies with new strands
• two identical molecules, each with 1 original strand and one new.
