Arrange the following events in the correct temporal sequence during eukaryotic cell division, starting with the earliest

(a) condensation of the chromosomes, (b) movement of chromosomes to the poles, (c) duplication of the chromosomes, (d) formation of the nuclear membrane, (e) attachment of microtubules to the kinetochores, (f) migration of centrosomes to positions on opposite sides of the nucleus. Answer is: c, f, a, e, b, d

Match the stages of mitosis with the events they encompass

Stages: (1) anaphase, (2) metaphase, (3) prophase, (4) telophase. Events: (a) reformation of the nucleolus, (b) disappearance of the nuclear membrane, (c) condensation of the chromosomes, (d) formation of the mitotic spindle, (e) movement of chromosomes to the equatorial plane, (f) movement of chromosomes to the poles, (g) decondensation of the chromosomes, (h) splitting of […]

In what way do the microtubule organizing centers of plant and animal cells differ?

The microtubule-organizing center (MTOC) is a hollow cylinder structure from which microtubules become prominent. Both plant and animal cells have MTOC microtubule organizing centers. Animal cells have centrioles associated with microtubule organizing centers. This complex is called as centrosome. Plant cells do not have centrioles but have MTOC. Therefore, microtubule organizing centers will not associate […]

Which typically lasts longer, interphase or M phase? Can you explain why one of these phases lasts longer than the other?

Answer: Interphase Because synthesis of DNA and other materials must be synthesized for the cell division. Explanation: Cell cycle includes growth of cells, copying its genetic material (DNA), and then physically divide into two daughter cells. It is important to know the length of the cell cycle as it determines multiplication rate of an organism. […]

With a focus on the chromosomes, what are the key events during interphase and M phase in the eukaryotic cell cycle?

In eukaryotic cells, the cell cycle is divided into two stages. These are interphase and the mitotic (M) phase. M phase includes mitosis and cytokinesis. Cell cycle includes growth of cells, copying its genetic material (DNA), and then physically divide into two daughter cells. During interphase, growth of cell and then copying of its DNA […]

Compare the sizes and structures of prokaryotic and eukaryotic chromosomes.

Compare the sizes and structures of prokaryotic and eukaryotic chromosomes. Size: Eukaryotic chromosomes are typically larger than prokaryotic chromosomes. Structure: Prokaryotic chromosomes are closed circular polymer and eukaryotic chromosomes are linear polymer. Prokaryotic chromosomes are circular, therefore migrate faster in gel as compared to linear chromosomes of eukaryotes. This is because they prokaryotes chromosomes has […]

Difference Between Prokaryotic and Eukaryotic cell

  Difference Between Prokaryotic and Eukaryotic cell What is the difference between prokaryotic and eukaryotic cell. Read the points for the answer 1) It is believed that prokaryotic cells are the most primitive cells. Eukaryotes have been evolved from the prokaryotes. 2) Prokaryotic cells are unicellular organisms. Eukaryotes may be either unicellular or multicellular organisms. Eukaryotes are of four types: animals, […]
