In what part of the cell cycle does the DNA make a copy of itself?

• Interphase

• Prophase

• Telophase

• Cytokinesis

Which pair of nitrogenous bases will form a bond in a DNA molecule?

• cytosine and adenine

• adenine and thymine

• guanine and thymine

• thymine and cytosine

What three components make up a nucleotide?

• a deoxyribose, a phosphate, and an enzyme

• a phosphate, an enzyme, and a nitrogenous base

• an enzyme, a deoxyribose, and a nitrogenous base

• a phosphate, a deoxyribose, and a nitrogenous base

Which nitrogenous bases are needed to complete the DNA strand pictured below? Give your answer in order, from top to bottom.

• thymine, adenine, guanine, cytosine

• adenine, thymine, guanine, cytosine

• adenine, thymine, cytosine, guanine

• cytosine, guanine, thymine, adenine

When one DNA molecule is replicated, the result is two DNA molecules. What is true of the second DNA molecule?

• It is identical or nearly identical to the first DNA molecule.

• The sequence of bases, from top to bottom, is opposite the sequence in the first DNA molecule.

• It is half the size of the first DNA molecule.

• It is twice the size of the first DNA molecule.

What is the role of enzymes in the DNA replication process?

• Enzymes read the DNA code and build a new DNA molecule from scratch.

• Enzymes link together to form a template for a new DNA molecule to be built.

• Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.

• Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA
