Exam 9: The Links in Lifes Chain: Genetics and Cell Division

If a cell with two nuclei were discovered, which of the explanations below would be true?

A cell plate is forming across the middle of a cell and new nuclei are forming at the poles. What kind of cell is this?

Refer to the figure below, and then answer the question that follows. -A cell that no longer needs to divide will remain in G₀ phase. But if an injury occurs to an organ, signals will tell the cell to return to the cell cycle to replace lost or damaged cells. To which point in the cycle will the cell return, and which phase would it enter next?

Bacterial binary fission is essentially the same process as mitosis in animals and plants.

List and briefly describe three differences between prokaryotic and eukaryotic cell division.

While looking under a microscope, you see two neighboring daughter cells. One of the cells contains three chromosomes, and the other contains five. The parent cell normally contains four chromosomes. What could be the reason for the different number of chromosomes in the cells?

The chief accomplishment of telophase is the organization of chromosomes into new nuclei.

What would be the result of an error in anaphase that failed to separate a pair of sister chromatids?

In cell division, the separation of the cell's cytoplasm to produce two daughter cells is ________.

Match the following. A) metaphase B) telophase C) prophase D) cytokinesis E) anaphase -Chromosomes condense and the mitotic spindle begins to form

The sequence of events from the birth of a cell to when it divides describes the ________.

Human skin cells and human white blood cells of the immune system both perform protective functions. Skin cells function primarily in external physical protection, whereas white blood cells function primarily in internal protection. Nonetheless, both types of cells contain a complete copy of the human genome. Explain how cells can have the same genetic information and yet perform different functions. What prevents skin cells from making all the same proteins of a white blood cell?

Anaphase is characterized by the separation of sister chromatids.

How do daughter cells at the end of mitosis and cytokinesis compare with the parent cell before DNA replication occurs?

What is the relationship between genes and proteins, including the function of each?

A gene is a hereditary unit that carries information for:

The "gap" phases of the cell cycle are devoted to:

Match the following. A) metaphase B) telophase C) prophase D) cytokinesis E) anaphase -Chromosomes unwind and new nuclei form

Which cell cycle stage is not part of interphase?

When a dividing human cell reaches telophase, 23 nuclear membranes must form, one for each pair of chromosomes.
