What treatment is being compared to the control in an experiment?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment).
What treatment is being compared to the control in the experiment the treated glioblastoma cells were stained with a fluorescent dye But the control cells were not stained?
Terms in this set (68) What treatment is being compared to the control in the experiment? The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
Which statement best describes the difference in the distribution of cells in the treated sample compared to the control sample?
Which statement best describes the difference(s) in the distribution of cells in the treated sample compared to the control sample? The treated cells are mostly in the G1 phase (region A), but in the control sample, there are peaks of cells in both G1 and G2 (region C).
Which is the best explanation of how the activity of a cell is controlled?
Which is the best explanation of how the activity of a cell is controlled? a. Cells are controlled by checkpoints that keep them from dividing until the proper preparations and conditions exist.
What hypothesis was being tested with the δFus3 strain?
The ΔFus3 strain should not form shmoos, and the cells should not have a red zone in their walls. One of their hypotheses was that formin is required for the signal transduction pathway leading to shmoo formation.
How do cells become differentiated mastering biology?
How do cells become differentiated? Different genes are expressed so that different proteins are produced. The DNA in each cell changes so that the appropriate proteins are produced. Paternal effect genes begin the process of differentiation by providing positional information.
Which of the following best describes the cells that result from the process of meiosis in mammals?
Assuming that meiosis occurred in a mammal, which statement best describes the cells that resulted? They are genetically different from the parent cell.
Which of the following best describes how the amount of DNA in the cell changes during M phase?
Which of the following best describes how the amount of DNA in the cell changes during M phase? The amount of DNA is halved as the cell divides into two daughter cells.
Which statement best describes the difference between bacterial cells and human cheek cells?
What is the difference between the size and shape of the bacteria cells and the cheek cells? Cheek cells are much larger than the bacteria cells. The bacteria cells are found INSIDE the cheek cells.
What is the control system of the cell?
The central components of the cell-cycle control system are cyclin-dependent protein kinases (Cdks), whose activity depends on association with regulatory subunits called cyclins. Oscillations in the activities of various cyclin-Cdk complexes leads to the initiation of various cell-cycle events.
How is the cell cycle controlled what would happen if the control were defective?
The cell cycle is controlled by a check point system. If this control were defective then the cells would divide uncontrollably, like cancer.
What is the control center of the cell?
The nucleusThe nucleus is like the remote control center of the cell. It acts as the cell's brain by telling it what to do, how to grow, and when to reproduce. The nucleus is home to the cell's genes.
Answer
The correct answer is: the treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor .

How were control glioblastoma cells treated?
d. The control glioblastoma cells were run through the flow cytometer and then treated by being cultured in the presence of an inhibitor.
Can glioblastoma cells be cultured without an inhibitor?
B. The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
What phase are treated cells in?
The treated cells are mostly in the G1 phase (region A), but in the control sample, there are peaks of cells in both G1 and G2 (region C). What does the difference in distribution tell you about the cells in the treated sample? The treated cancer cells are arrested at the G1 phase. Which mechanism is the best explanation for how ...
What phase are cancer cells arrested?
The treated cancer cells are arrested at the G1 phase.
Does DNA change in S phase?
No; the DNA content per cell changes as the S phase progresses, so the cells in S phase have a range of fluorescence levels.
Is there a correlation between fluorescence and DNA?
The x-axis; the DNA was stained, so there is a positive correlation between fluorescence and DNA content.
Can glioblastoma cells be cultured without an inhibitor?
The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
How is cytokinesis accomplished in animal cells?
Cytokinesis in animal cells is accomplished by constriction of the cell along the plane of cell division (formation of a cleavage furrow). In plant cells, which have cell walls, a completely different mechanism of cytokinesis has evolved.
What is the cell cycle?
The cell cycle represents the coordinated sequence of events in the life of a cell from its formation to its division into two daughter cells. Most of the key events of the cell cycle are restricted to a specific time within the cycle. In this exercise, you will identify when various events occur during the cell cycle.
How does mitosis unfold?
Mitosis unfolds through a sequence of stages marked by specific events in the cell. The structural changes in the cell are brought about by a series of tightly coordinated underlying mechanisms. Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs.
What is the first step in preparing for division?
The first step in preparing for division is to replicate the cell’s DNA in the S phase. In the G2 phase, the centrosome replicates. In early M phase, the centrosomes move away from each other toward the poles of the cell, in the process organizing the formation of the mitotic spindle.
