Exam 10: Cell Division and Mitosis

Contact inhibition is an important mechanism for maintaining cell growth in developed organs and tissues. As long as the cells maintain contact with each other, they remain in ____ and are prevented from dividing.

Early in mitosis, chromatin condenses. Which process takes place more easily as a result?

Binary fission ____.

Bacterial cells typically have ____ while eukaryotic cells have ____.

Experiments that led to the understanding of cell cycle control were performed on yeast.

If a diploid cell with 40 chromosomes undergoes meiosis, each daughter nuclei will have ____ chromosomes.

At the conclusion of mitosis, each daughter cell has ____.

What is the purpose of mitosis in living organisms?

Mitotic cyclins bind to S-phase Cdks in G₂, which is required for the progression of the cell through mitosis.

An organism with a chromosome number of n =7 is said to be haploid.

The microtubule organizing center (MTOC) of an animal cell is an identifiable structure known as the ____.

How many unique chromosomes does an organism with a chromosome number of 4 n =32 have? Assume that none of these are sex chromosomes, and do not count any duplicate homologous chromosomes in this number.

The tight packing of chromatin into the chromosomes visible during nuclear division is possible due to links between ____ proteins.

How is cell division different in plants versus animal cells?

When plants are produced by cloning, which process is most directly involved?

Where is the centromere found?

Chromatin condenses into chromosomes and the mitotic spindle begins to form during ____.

If a cell has 36 chromosomes at the beginning of G₁, how many chromosomes will be present at the end of G₂?

Sister chromatids connect at a region of DNA called the centrosome.
