During which phase does the cell actually separate into two individual daughter cells?
Prophase
Cytokinesis
Interphase
Metaphase
If your were to examine a sample of 1000 cells, in which of the phases listed below would you expect to find most of the cells?
Interphase
Metaphase
Anaphase
Telophase
Upon examining a sample consisting of 100 cells, you find the following distribution of cell phases. If you know that the cell cycle for this type of cell takes two hours, how long, on average, does the cell spend in prophase?
8 minutes
16 minutes
22 minutes
30 minutes
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

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
