Homework Answers
26. In plants cell wall forms between the daughter cells while in animals a cleavage furrow forms. Cytokinesis starts in anaphase in animal cells and prophase in plant cells, and ends in telophase in both cells to produce the two diploid daughter cells each with one nucleus.
Thus, the correct answer is option a.
27. the major targets of Anaphase-Promoting Complex are securin and S & M cyclins. Securin releases a cysteine protease, separase.
Thus, correct answer is securin.
28. Sister chromatids are able to move freely to opposite poles for anaphase as securin undergoes ubiquitisation by the APC / C and releases separase, which degrades cohesine.
Thus, the correct answer is cohesin.
29. A somatic cell is diploid and has the same DNA like every other somatic cells and also has same DNA like a zygote, i.e., both are diploid.
Thus, the correct answer is obtion b.
30. P53 helps to inhibit tumor growth by preventing damaged or mutated cells from division. p53 is important for the control of DNA repair and cell division, it is also known as "guardian of the genome."
Thus, the correct answer is option b.

Question 19 (Mandatory) (2 points) Saved How is plant cell cytokinesis different from animal cell cytokinesis? The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. The structural proteins of plant cells separate the two...

Question 1 1 pts A plant-derived protein known as colchicine can be used to poison cells by blocking the formation of the spindle. Which of the following would result if colchicine is added to a sample of cells in G2? The chromosomes would segregate but in a disorderly pattern. The chromosomes would still line up along across the middle of the cell, but the chromatids would not end up segregating The cells would immediately die. Each resultant daughter cell would...
