- Figure 6.4 Which of the following is the correct order of events in mitosis? a. Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the initotic spindle. The nucleus re-forms and the cell divides. The sister chromatids separate. b. The kinetochore becomes attached to the mitotic spindle. The sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus re-forms and the cell divides. c. The kinetochore becomes attached to metaphase plate. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus re-forms and the cell divides. d. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. The kinetochore breaks apart and the sister chromatids separate. The nucleus re-forms and the cell divides.Human somatic cells have 46 chromosomes. Are the cells different in any way from the parent cell and what is chromosome count of each of those cells once they have finished mitosis?In mice, 2n = 40. If a mouse cell divides by mitosis, it will produce two daughter cells that each have ________ chromosomes. If a mouse cell divides by meiosis, it will produce four daughter cells that each have ________ chromosomes. Type the appropriate number to fill in each blank (e.g., 40).
- Meiosis and germ cell formation in cell with four choromossomes can you see how chromosome segrate when germ cell are formed?In a turtle species, a diploid cell in the G1 phase of the cell cycle contains 22 picograms of DNA (picogram is a measure of the total mass of the DNA present). How much DNA is present in a cell of the same species at prophase II of meiosis (prophase of the second meiotic division)?At the end of Meiosis II in human cells (specifically in males, for example), how many gametes are made from one original parent cell, how many chromosomes are in each gamete, and what is each chromosome made of (that is, if you compared, say, chromosome #1 in a gamete with the two #1 chromosomes the person inherited from his parents)?
- Humans have 46 chromosomes in each somatic cell. a. How many chromosomes does a child receive from its father?A dog has78 chromosomes . How many chromosomes will a cell have after it goes through mitosis? And how many chromosomes will dog have after going through meiosis?Somatic cells of chimpanzees contain 48 chromosomes. During metaphase I of meiosis, a chimpanzee cell will contain ____ chromosomes, ______ chromatids, and _______ bivalents. Fill in each blank with the appropriate number (e.g., 48).
- 38. Ture or False- Throughout mitosis, sister chromatids are identical, but sister chromatids are not identical to each other throughout meiosis.Normal events in mitosis gives rise to daughter cells with exactly the same chromosome number and genetic material. What may be expected to happen chromosomally and genetically to: 1. a cell with a chromosome that contains two centromeres?Mitosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of mitosis. Make sure to draw the alleles for genes A and B on the chromatids in every stage. For mitosis, remember that many events are going on in the cell that are relevant besides just the movement of chromosomes, so please fill in the cell with pertinent structures such as centrioles and spindles.
