- How long does it take for a cell to take one complete cycle? The answer varies on the type of cell and the species. For instance, a liver cell completes its cell cycle for over 22 hours (Becker and Lane 1965) while other somatic cell lasts to about 18 hours. Can you cite other types of cells that undergo cell cycle and the time it takes to complete the cycle? List five below.arrow_forwardWhich of the following is true of normal adult cells but NOT cancer cells? A. Cell death after a finite number of cell divisions B. Contact with other cells increases likelihood of division C. Large amount of telomerase present D. Do not care about cell density while culturearrow_forwardExplain the following figure.

Why do cancercells kill normal cells of the body?arrow_forwardWhich of the following statements about cell division in prokaryotes and eukaryotes is correct? a. In prokaryotes, all cells divide if conditions are favourable; in eukaryotes, only a few cells divide, and they do so according to a developmental program b. After cell division, the daughter cells are genetically identical in prokaryotes but genetically different in eukaryotes c. In prokaryotes, only a few cells divide to ensure survival of the colony without depleting too many resources from the environment d. The process of segregation is more complicated in prokaryotes than in eukaryotes e. Reproductive signals for initiation of cell division are intracellular for prokaryotes and extracellular for eukaryotesarrow_forwardWhat is different about mitosis in the plant cell as compared to the animal cell? Give two differences. please do not copy from google and explain wellarrow_forward
- Which of the following statements correctly identifies the difference between plant and animal cell division? Select one: a. The cell walls of plants prevent the process of cytokinesis. b. Plants cells lack centrioles, and they form a cell plate during cytokinesis. c. Both plant and animal cells undergo mitosis and cytokinesis, but they lack the interphase. d. Plant cells lack centromeres, and they form a cell wall to produce two daughter cells.arrow_forwardWhat is different about mitosis in the plant cell as compared to the animal cell? Give two differences. please explain and do not copy from googlearrow_forwardYou are interested in testing the effect of a drug on human cells. These cells have been sampled and evenly split into two separate cell cultures. You trigger cell division using a growth factor in both cell cultures. This synchronises the start of mitosis so you can easily detect the effect of the drug on the progress through the mitotic phases. Immediately after mitosis begins, you expose one cell culture to the drug (treatment + drug) and compare their progress through the mitotic phases under the microscope to the cells that are not exposed to the drug (control - drug). Here are your observations: Cells from both cell cultures lack their nuclear membranes. Individual chromosomes are clearly visible in both cell cultures Cells from the control culture (- drug) have their chromosomes aligned (see figure below) Cells from the treatment (+ drug) have their chromosomes dispersed in the cell (see figure below). What effect does the drug have on the chromosomes? Indicate two…arrow_forward
- Explain what sets the lower limit of the cell size and the upper limit.arrow_forwardA scientist adds colchicine, a microtubule polymerization inhibitor, to a cell entering mitosis. At metaphase, the chromosomes of the cell were arranged as shown below. Explain why this arrangement is consistent with the application of colchicine. Predict how colchicine would affect the cell as it attempts mitosis.arrow_forwardAn enzyme such as ligase is a protein molecule. When high temperature is applied to ligase, the protein molecule changes its shape and is no longer able to perform its function. The enzyme is said to be denatured. If ligase was denatured in a cell, how would it affect its cell cycle? Select one: a. The cell would not be able to obtain amino acids. b. The cell would not be able to transcribe DNA. c. The cell would not be able to produce protein molecules. d. The cell would not be able to replicate.arrow_forward
