Which best describes what would happen if the double helix structure of DNA could not be “unzipped”?

• DNA replication would not occur.

• DNA replication would occur more frequently.

• DNA replication would occur at the same rate.

• DNA would replicate only half of its nucleotides.

In which part of a Eukaryotic cell does DNA replication occur?

• cytoplasm

• nucleus

• ribosome

• vacuole

What is the name given to the spiral structure including complimentary nucleotide strands making DNA?

• RNA

• nucleotide

• double helix

What aspect of DNA replication allows it to be considered a semiconservative process?

• DNA replication occurs at an extremely slow rate.

• DNA replication only duplicates nucleotides in pairs.

• Each replicated strand of DNA is an old strand paired with a new strand.

  variations.

A nucleotide is the monomer of nucleic acids. It is made up of three parts:

a phosphate, a 5-carbon sugar and a nitrogenous base. According to the

base pair rule for DNA, Adenine pairs with:

• Thymine

• Guanine

• Cytosine
