DNA replication

Match he nucleotide with its complementary nucleotide. (DNA to DNA).

Adenine -

• Thymine

• Guanine

• Cytosine

Match he nucleotide with its complementary nucleotide. (DNA to DNA).

Cytosine-

• Thymine

• Guanine

• Adenine

If a strand reads:
3' A A A T T T C 5'
The matching strand would read...

• 5' T T T A A A G 3'
• 3' T T T A A A G 5'
• 5' A A A T T T C 3'
• 3' U U U A A A G 5'

3' and 5' refer to...

• How effectively the helicase works
• What direction the nucleotides are pointing
• Where the RNA primer attaches
• Okazaki's famous experiment

What is the shape of DNA?

• Double helix
• Triple helix
• Flat, bilayer
• Three-pronged rigid ladder

DNA replication turns one strand of DNA into two new strands of DNA. What percent of each new strand is the old strand?

• Half of each new DNA is the old DNA
• The old strand of DNA was digested, so none
• The new DNA is entirely made up of the old DNA
• About every sixth base comes from the old DNA

What is the purpose of DNA replication?

• Cut the DNA 
• Make more cells
• Apoptosis
• Duplicate the DNA

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

Which of the following is required for DNA replication to occur?

• DNA helicase
• DNA ligase
• DNA polymerase
• all of these
