Exam 11: The Cell Cycle and Cell Division

Knowledge of the cell cycle has led to improved means of treating cancer.Taxol, which prevents the microtubules of the spindle fiber from functioning normally, prevents the cell cycle from entering

Which statement about mitosis-associated microtubules is false?

If n is the haploid number of chromosomes, a trisomic individual has a total of _______ chromosomes.

What is the order of events for cell division in prokaryotes and eukaryotes?

The product of a gene inhibits cyclin production.Thus, it is most likely

Chromatin is most like beads on a string during _______.At this stage, it is the _______ densely packaged.

Which structure is primarily involved in determining the direction of movement of sister chromatids during mitosis?

A monosomic individual has 27 chromosomes.What is the haploid chromosome number?

Bacteria typically have _______, whereas eukaryotes have _______.

Which statement about sister chromatids is false?

Which situation would most likely result from a mutation in the ori gene of a bacterial cell?

Occasionally, a homologous chromosome pair fails to separate during anaphase I of meiosis.One of the resulting cells lacks a copy of this chromosome, whereas the other contains both members of the homologous pair.These abnormal cells are called _______ cells.

During bacterial cell division, a single cell is separated into two cells by

Refer to the figure showing nuclei of somatic cells of a diploid organism with varying chromosomal makeup. Image _______ best represents the chromosomal makeup of a daughter cell after telophase II and cytokinesis have occurred.

How does cytokinesis differ in animal and plant cells?

The orderly distribution of genetic information occurs in prokaryotic cells by a process known as binary _______.

Refer to the figure showing two sexual life cycles. Bald eagles reproduce through _______ cycle, the fertilized bird egg is _______, and the _______ stage of the life cycle is represented within the eggshell.

Cyclin-dependent kinases (Cdk's) catalyze the phosphorylation of targeted proteins, a process that

Your cell culture experiments are failing because the cells are dying.You want to know why and so decide to determine whether necrosis or apoptosis is occurring.The results show you that there are DNA fragments that are multiples of 180 bp in length, so you conclude that the cells are undergoing _______.

Which statement about benign tumors is true?
