Cell Growth and Reproduction Pre-Quiz
1. Cellular division involves the redistribution of the nuclear material, or DNA, as well as the cytoplasm and organelles. During which of the following processes is the nuclear material divided?
I. / cytokinesisII. / meiosis
III. / mitosis
/ A. / II and III only
/ B. / II only
/ C. / III only
/ D. / I, II, and III
2. During the interphase stage of the cell cycle,
/ A. / the cell's chromosomes are duplicated./ B. / the cell's chromosomes condense into rod-like structures.
/ C. / the cell divides into two unique daughter cells.
/ D. / the cell divides into two identical daughter cells.
3. Cells experience distinct cycles of activities, such as growth and division. These activities are summarized in the image below.
Beginning in the G1 phase, proteins called cyclins begin to accumulate in the cell. Cyclins combine with certain molecules to form cyclin-dependent kinase complexes (Cdkcs), which activate and deactivate other cellular proteins.
For example, cyclin B forms a Cdkc that controls the M stage of the cell cycle. This Cdkc turns on the proteins that are involved in mitosis, turns off the proteins that prevent mitosis, and even activates an enzyme complex that breaks down cyclin B. The loss of cyclin B signals the end of the M portion of the cycle. Notice that the concentrations of cyclin B peak during the mitosis stage.
Based on the above graph, which cyclin forms the primary Cdkc that controls the G2 stage?
/ B. / Cyclin B
/ C. / Cyclin A
/ D. / Cyclin D
4. The cytoplasm and two nuclei that are formed during mitosis are separated into two identical daughter cells during______.
/ A. / meiosis/ B. / cytokinesis
/ C. / prophase
/ D. / interphase
5. Before a cell enters mitosis, what happens to the genetic information in that cell?
/ A. / The information is selectively mutated./ B. / The information is halved.
/ C. / The information is duplicated.
/ D. / The information is completely changed.
6. Through the process of meiosis, sex cells are produced that are
/ A. / unique with a full set of genetic information./ B. / identical with a full set of genetic information.
/ C. / identical with a half set of genetic information.
/ D. / unique with a half set of genetic information.
7. The diagram below represents a stage of mitosis in which the chromosomes line up in the middle of the cell.
What is the name of this phase of mitosis?
/ A. / prophase/ B. / telophase
/ C. / metaphase
/ D. / anaphase
8. Which animal cell type undergoes meiosis?
/ A. / reproductive cells only/ B. / heart cells only
/ C. / all cells
/ D. / non-reproductive cells only
9. The cell cycle involves the growth, replication, and division of a eukaryotic cell.
Mitosis most directly plays a role in
/ A. / the metabolic processes of a cell./ B. / the growth of a cell after cell division.
/ C. / the division of a cell's nucleus.
/ D. / the transport of nutrients within a cell.
10. During the cell cycle,
/ A. / DNA is replicated directly after the completion of mitosis./ B. / DNA is replicated before mitosis begins.
/ C. / DNA is replicated once before and once after mitosis.
/ D. / DNA is replicated during mitosis.
11. Proteins play a variety of roles within cells, but there are many steps that must be undertaken to make these proteins and deliver them to where they need to go.
The above picture implies that
/ A. / only the organelles shown in the picture are important to cells./ B. / organelles must interact with each other to synthesize and transport proteins.
/ C. / no organelles are necessary for the synthesis and transportation of proteins.
/ D. / organelles act independently when synthesizing and transporting proteins.
12.
During the process shown above, the two strands of one DNA molecule are unwound. Then, DNA polymerases add complementary nucleotides to each strand which results in the formation of two identical DNA molecules.
This process is known as DNA______.
/ B. / cloning
/ C. / translation
/ D. / replication

/ A. / DNA elongation/ B. / DNA transcription
/ C. / DNA replication
/ D. / DNA translation
15. The nucleotide of DNA is one large molecule composed of three smaller molecules. Which of the following sets of molecules bond together to form a nucleotide?
/ A. / deoxyribose, a nitrogen base, a phosphate group/ B. / a nitrogen atom, a phosphate atom, and a five-carbon sugar
/ C. / a purine, a pyrimidine, and a five-carbon sugar
/ D. / adenine, thymine, and cytosine
