Question
Chapter 15.1, Problem 3EQ
Summary Introduction
To describe: The differences between results with 2 hour exposed donor oocytes and 12 hour exposed donor oocytes.
Introduction: Yoshio Masui and Clement Markert studied the effect of progesterone on frog oocytes. Oocytes are the cells that on maturity turn into egg cells. Progesterone is the hormone produced by female frogs during mating season. These researchers considered progesterone as a signaling molecule that affects the functions as well as the amount of proteins which guides the advancement of frog oocytes from G2 to the initiation of the M phase

Praeuce problem
Using the diagram from the Cell Cycle lesson,
we can practice calculating a mitotic index.
1. Count the number of cells that are in ANY
stage of mitosis (PMAT).
2. Count the total number of cells.
3. Use the Mitotic Index formula to calculate
the mitotic index for this sample.
Cells in mitosis:
# of cells in mitosis is
Total # of cells is
MI= # of cells in any stage of mitosis
MI=
Total number of cells
MI=

- Question: How many chromosomes were present before mitosis? How many chromosomes did each of the daughter cells contain after mitosis? Cite an example of a type of cell that undergoes mitosis. Why is it important for each daughter cell to contain information identical to the parent cell? Human skin cells divide at a higher rate than neurons (nerve cells). Hypothesize why this may be. Hypothesize what would happen if the sister chromatids did not split equally during anaphase of mitosis.arrow_forwardlook at the screenshot pleasearrow_forwardSCS 20-21_SCI_BIO_CFA2 Brewer, Elise 10 of 24 6. A student observed onion cells in various stages of cell division. The results of two samples are shown in the table. Cell Division in Onions Stage of Second Sample First Total Number Cell Cycle Sample Interphase 44 45 89 Prophase 2 Metaphase 1 2 Anaphase 1 Telophase Total number of cells counted 100 Based upon the data, what can be correctly concluded? O Cell division in onion cells is highly regulated, with each cell dividing at the same time. O Onion cell division is slow compared to animal cells. O Onion cells spend more time in interphase than any other phase of the cell cycle. O Prophase is the longest phase of the cell cycle in onion cell division.

- Please give me an example on what to research!arrow_forwardObjective: To review the phases of mitosis with the understanding that in a real tissue or a non-synchronized cell culture, different mitotic phases and cells in interphase will be observed at a certain time. Interphase is the period between mitotic events; all other phases are part of mitosis and their individual probabilities add up to the total probability of seeing cells undergoing mitosis. Pay attention to the individual probabilities for cells in each phase of the cell cycle. Problem N° 10 For a certain type of animal tissue, the probability of a randomly selected cell being in a particular stage of the interphase/mitosis cycle is given by the following table: Stage Probability Interphase 0.5 Prophase 0.1 Metaphase 0.05 Anaphase 0.2 Telophase 0.15 Suppose you examine 100 cells at random from this tissue.
