1

Adenine and guanine are

1

Which statement is true?

The hydrogen bonding of cytosine to guanine is an example of complementary base pairing.

Adenine always pairs up with guanine in DNA, and cytosine always teams up with thymine.

Each of the four nucleotides in a DNA molecule has the same nitrogen-containing base.

When adenine base pairs with thymine, they are linked by three hydrogen bonds.

In the DNA of all species, the amount of purines never equals the amount of pyrimidines.

Each DNA strand has a backbone the consists of alternating

1

The appropriate adjective to drescribe DNA replication is

1

Replication of DNA

produces RNA molecules

produces only new DNA

produces two molecules, each of which is half- new and half - old DNA joined lengthwise to each other.

generates excessive DNA, which eventually causes the nucleus to divide.

is too complex to characterize

This is an image of a(n) ______.

amino acid

nucleic acid

DNA

nucleotide

1

Nucleic acids are assembled in the ______ direction.

Match the following enzyme to its description.

Draggable item		Corresponding Item
helicase		Joins the 3’ end of DNA that replaces primer to rest of leading strand and joins Okazaki fragments of lagging strand
DNA ligase		Removes RNA nucleotides of primer from 5’ end and replaces them with DNA nucleotides
Primase		Binds to and stablizes single stranded DNA until it can be used as a template.
DNA polymerase I		Synthesizes an RNA primer at 5’ end of leading strand and of each Okazaki fragment of lagging strand
Single Stranded Binding Proteins		Using parental DNA as a template, synthesizes new DNA strand by covalently adding nucleotides to the 3’ end of a pre existing DNA strand or RNA primer.
DNA polymerase III		Unwinds parental double helix at replication forks
