Question

You have isolated DNA from three different cell types of the same organism determined the relative DNA content for each type, and plotted the results on the graph shown in the figure below. Refer to the graph to answer the following question (s). 31) which sample of DNA might be from a cell in G1 or G0 of the cell cycle? A) I B) II C) III 32) which sample of DNA might be from an egg or sperm cell? A) I B) II C) III D) Both I and II 33) Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants A) a cell plate begins to form at telophase, whereas in animals a cleavage furrow is initiated at that stage. B) spindle poles contain centrioles, whereas spindle poles in animals do not. C) chromosomes become attached to the spindle at prophase, whereas in animals chromosomes do not become attached until anaphase. D) the spindles contain microfibrils in addition to microtubules, whereas animal spindles do not contain microfibrils. from one another in animals. E) sister chromatids are identical, but they differ

Explanation / Answer

31. in G1 phase of the cell cycle the DNA Content is low. So option C is correct .

32.The egg cell or the sperms cell is full with genetic material DNA. So option B is correct .

33.in higher plants due to presence of cell wall cell plate is formed between two new cells where as in animal cells cleavage furrow is formed.

So option A is correct .
