Quiz: DNA Replication

What are the building blocks of DNA?

• Nucleotides
• Nuclei
• Nucleic Acid
• Noodles

What are the 2 strand of DNA connected in the middle with?

• Covalent Bonds
• Hydrogen Bonds
• James Bonds

Select all of the incorrect pairings below:

• Adenine - Thymine
• Cytosine - Guanine
• Guanine - Cytosine
• Thymine - Adenine
• Thymine - Guanine

What must you do to a DNA strand in order to make a duplicate strand?

• Use the old strand, make a copy and toss out the old one
• Unzip the old strand, add the new parts to the old piece so each new molecule has one piece of the old and one piece of the new

• Unzip the old one and create hydrogen bonds between the old bases again after you have used it as a template.

The "backbone" of DNA consists of

• Just Sugar
• Sugars and Phosphates
• Nitrogenous Bases

Which is the correct order of the complementary pairs for the strand: ATTCGC

• ATTCGC
• GCCATA
• TAAGCG
• CGGTAT

What is the job of the helicase and polymerase enzymes?

• Helicase unzips and polymerase put the new ones together
• Polymerase unzips and helicase puts the new ones together
• Polymerase does everything
• Helicase does everything

If there are 30 Adenine on the DNA molecule, use Chargaff's rule to determine the amount of the other bases.

• There are 30 Guanine
• There are 20 Cytosine
• There are 20 Adenine
• There are 20 Thymine

Why is DNA replication considered "semi-conservative"?

• The old strand stays together the entire time
• The old strand is used as a template for the new strands
• The new strand deletes pieces from the old one

Where is the DNA located in a prokaryotic cell (like a bacteria)?

• The nucleus
• Free-floating in the cytoplam
• In the nucleotide
• In the nucleolus
