Document Summary

How many daughter cells are produced: 2 daughter cells. Are the daughter cells identical to each other, or the parent cell (cell that underwent mitosis): each daughter cell is identical to the other, understand all of the stages of meiosis i and ii. How many daughter cells are produced by meiosis i: 2 daughter cells are produced. Are the daughter cells identical to each other, or the parent cell: they are not identical to each other, and not the parent cell, because they each carry half of the parent cell"s genetic material. How many daughter cells are produced by meiosis ii: 4 haploid daughter cells are produced. Sister chromatids separate: what separates during meiosis i (homologous chromosomes, or sister chromatids), what separates during meiosis ii (homologous chromosomes, or sister chromatids), what are kinetochores, explain the difference between sexual and asexual reproduction. Protein structures on chromosomes where spindle fibers attach during mitosis.

Describe the process of mitosis and cytokinesis. Your answer should provide specific
information on: 1) the primary events that occur during interphase, specifically those that take
place to prepare a cell for mitotic division; 2) the specific stages of mitosis and the events that
occur in each stage; 3) the primary events during cytokinesis in plant and animal cells as the
content of the cytoplasm is divided between the daughter cells.

Part A:

In prokaryotes and eukaryotes cell reproduction is similar in that it requires some kind of signal to proceed, DNA replication, careful separation of the DNA into two equal portions, and division of the cytoplasm. How is cell reproduction different in prokaryotes and eukaryotes?

Select one:

a. In a eukaryotic organism, the signals for cell division are usually not related to the environment but to the function of the entire organism.

b. Eukaryotic cells constantly divide whenever environmental conditions are adequate and the cells are large enough.

c. The linear chromosomes in prokaryotes are constantly being updated.

d. Prokaryotic cell division requires cytokinesis before mitosis because of their small size.

e. The sexual phase of most prokaryotes (bacteria) is essential to the rapid cell division required for infection.

Part B:

What does the name Cyclin Dependent Kinase stand for?

Select one:

a. A protein important to the cell cycle that is dependent on DNA synthesis.

b. An enzyme that cuts DNA so that chromosomes can segregate.

c. An enzyme that phosphorylates other proteins using ATP only when the protein Cyclin is bound to the enzyme.

d. An enzyme that rolls along microtubules dragging a vesicle.

e. An enzyme that connects chromosomes to the spindle fiber.

Part C:

The Cell Cycle is divided into Mitosis, Cytokinesis, and Interphase. Mitosis can be ordered into the following phases:

Select one:

a. Prophase/Prometaphase/Metaphase/Anaphase/Telophase

b. Anaphase/Prometaphase/Metaphase/Prophase/Telophase

c. Metaphase/Anaphase/Telophase/Prophase/Prometaphase

d. Telophase/Prophase/Prometaphase/Metaphase/Anaphase

e. Anaphase/Telophase/Prophase/Prometaphase/Metaphase

Part D:

The Cell Cycle is divided into Mitosis, Cytokinesis, and Interphase. Interphase can be ordered into the following phases:

Select one:

a. S/G1/G2

b. G2/G1/S

c. G1/S/G2

d. G2/S/G1

e. G1/G2/S

Carefully read the following statements about cell division (1) After meiosis, the number of chromosomes in the newly formed cell is the same as that in the parent cell. Whereas, in mitosis, the chromosome number in daughter cell is reduced to half. (2) Cytokinesis is a highly regulated event in which cellular organelles are evenly distributed forming two daughter cells. (3) In Meiosis, DNA replication occurs only once whereas the cells divide twice and it is the mechanism that produces genetic variation in daughter cells. (4) In diplotene, chiasmata are formed between homologous chromosomes followed by crossing over and segregation of sister chromatids. (5)The kinetochore is a DNA protein complex which serves as the attachment point for spindle fibers. Which of the above statement or combination of statements is correct?
