3) This enzyme adds RNA primers onto the lagging DNA strand.
A
primase
B
ligase
C
polymerase
D
helicase
4) The lagging strand is the
A
5' to 3' strand
B
3 to 5 strand
C
3' to 5' strand
D
5 to 3 strand
5) The 5' to 3' strand lags because
A
this strand is protected by bulky ribosomes
B
this strand is longer than the leading strand
C
DNA can only be synthesized in the 3' to 5' direction
D
DNA can only be synthesized in the 5' to 3' direction.
6) The 3' to 5' strand leads because
A
the resulting DNA strand requires no proof reading.
B
this strand is not blocked by bulky molecules.
C
as it's copied, the resulting DNA strand is synthesized in the 5' to 3' direction
D
as it's copied, the resulting DNA strand is synthesized in the 3' to 5' direction
7) A strand of DNA is copied and the resulting copy was synthesized discontinuously. This synthesized DNA was copied from
A
the 3' to 5' strand
B
the 3 to 5 strand
C
the lagging strand
D
the leading strand
8) DNA replication is semi-conservative because
A
each replicated DNA molecule contains an original strand and a newly synthesized DNA strand
B
each strand of the DNA molecule is copied and the 2 copies come together to make an entirely new helix
C
the DNA molecule is copied using almost no ATP
D
each replicated DNA molecules contains two newly synthesized DNA strands
9) An RNA primer is required by the ______ strand.
A
chromosomal
B
lagging
C
leading

16) Hydrogen bonds are useful for DNA molecules because
A
they are fairly weak and allow the DNA molecule to be transported outside of the nucleus
B
they are incredibly strong and do not allow the DNA molecule to be readily separated
C
they are incredibly strong and allow the DNA molecule to be formed into chromosomes
D
they are fairly weak, allowing for the DNA molecule to be separated as needed
17) In RNA, uracil replaces
A
adenine
B
thymine
C
guanine
D
cytosine
18) DNA gets replicated for all of the following reasons except
