DNA Replication

Which sequence of DNA bases would pair with this partial strand
CAT TCA CTG

• ATG TGA CAG
• TAC ACT GTC
• GTA AGT GAC
• CAT TCA CTG

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

order of replication

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

NGSS.HS-LS3-2

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 identical molecules, each with 1 original strand and one new.

Why does DNA replicate?

• To create another copy for the new cell before cell divides.

• To create a duplicate copy in case the original gets damaged

• To stop protein synthesis from occurring.

Match the nitrogen base with its complementary nitrogen base. (DNA to DNA).

Adenine -

• Thymine

• Guanine

• Cytosine

If the percentage of DNA is made of 30% Thymine, what is the correct percentage of Adenine?

• 30

• 15

• 20

• 60
