1.
A process in which DNA has the unique ability to make an exact copy of itself.
a)
Replication
b)
Translation
c)
Transcription
2.

What is step 1 of replication?

a)

Nucleotides are added to the exposed bases on the DNA molecule

b)

The DNA molecule is unwound

c)

Nucleotides are broken off of the DNA molecule

d)

1 strand of the original DNA molecule is conserved in the new molecules

3.

What is step 2 of DNA replication?

a)

The DNA molecule is unzipped (hydrogen bonds are broken)

b)

Nucleotides are added to two template strands of DNA according to base-pairing rules

c)

Complementary strands are added to the template strands by DNA helicase

4.

What is step 3 of DNA replication

a)

DNA is wound to form a double helix once more

b)

Free-floating nucleotides are added to the exposed bases on each template strand

c)

DNA is unzipped

5.

What is step 4 of DNA replication?

a)

DNA is unzipped

b)

Nucleotides are added to the exposed bases

c)

DNA is unwound

d)

2 identical strands of DNA are formed

6.

What is the enzyme responsible for the unwinding and unzipping of the DNA molecule during replication?

a)

DNA polymerase

b)

DNA ligase

c)

DNA primase

d)

DNA helicase

7.

Which enzyme is responsible for adding nucleotides to the exposed bases during DNA replication?

a)

DNA ligase

b)

DNA primase

c)

DNA polymerase

d)

DNA helicase

8.
Which sequence of DNA bases would pair with this partial strand
CAT TCA CTG
a)
ATG TGA CAG
b)
TAC ACT GTC
c)
GTA AGT GAC
d)
CAT TCA CTG
9.

The new DNA strand formed after DNA replication is an exact copy of its parent strand

a)

True

b)

False

10.
Sometimes, DNA is called "semi-conservative." Why might this be?
a)

The old strand is "conserved" and used to make the new strands

b)
Uracil is "conserved" in that it is only used to make the new strands
c)
ATP is "conserved" via the usage of facilitated diffusion
d)
Ligase is "conserved" in that it is denatured by the process
