What provided the information for cell growth and function?
The DNA is the molecule that provides theinformation for cell growth and function.
Is an organism containing many cells how is the work of the cell performed?
Most of the cell cycle consists of a growth period in which the cell takes on mass and replicates the DNA. This is why the cell cycle is so important.
Which stages make up interphase of the cell cycle?
Interphase{G1 (cell growth), S (DNA is copied), G2 (growth and preparation for cell division)}, Cell Division {mitosis and cytokinesis} False
What happens when mitosis stops?
Yes, certain cells such as your brain and skeletal muscle cells stop cell division at or around the time of birth and are arrested in a phase of interphase called G0where they no longer divide.
What stage of mitosis does a cell spend most of it's life?
When we look at the cell cycle, we see that the genome doubles (replicates itself) during the S phase. Since the M (mitosis) phase comes after the S and G2 phases, prophase of mitosis has the maximum number of chromosomes. Here, there are two copies of the genome.
Of the four stages of mitosis which one takes the most time to complete?
The stage of mitosis that takes the longest time to complete is typically prophase. During prophase, the cell undergoes several complex changes, such as condensing its chromosomes and breaking down the nuclear membrane. These processes can be time-consuming compared to the other stages of mitosis.
What provided the information for cell growth and function?
The DNA is the molecule that provides theinformation for cell growth and function.
What complex of two proteins gives the ok signal for a cell to begin mitosis?
The complex of two proteins that gives the green light for a cell to enter mitosis is called the Cyclin-dependent kinase (Cdk) and Cyclin complex. This complex phosphorylates target proteins involved in initiating mitosis and drives the cell cycle forward.

What stage in mitosis does cell spend the most time in?
MitosisIntroductionThere are five main phases of Mitosis, plus one that is included to certain cell types.They are listed in order from:InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesisPrecursor to MitosisBefore mitosis is the phase in the cell cycle called interphase. This takes up 78% of the time in a cell's division cycle, and is the longest phase in the cycle.Interphase consists of the three subphases called G1, Synthesis, and G2.Prophase14% of the time in a cell's cycle is spent in the prophase.This is the second longest phase in the cell cycle, but the longest phase in actual mitosis. In prophase, the DNA supercoils into chromosomes, the nuclear membrane breaks down, and the centrioles move towards the opposite poles of the cell. The spindle microtubules also assemble.Metaphase4% of the time in a cell's cycle is spent in the metaphase.In metaphase, the spindle microtubules then attach to the centromeres of the chromosomes and the chromosomes then line up along the equator of the cell.Anaphase0.8% of the time in a cell's cycle is spent in the anaphase.This is the shortest phase in the cell cycle. In anaphase, the spindle microtubules shorten, the sister chromatids (two individual chromosomes paired and attached at the centromere) split into two identical chromosomes. The chromosomes are then pulled to the opposite poles of the cell proportionately.TelophaseRoughly 3% of the time in a cell's cycle is spent in the telophase.In the telophase, the chromosomes then unwind at their poles, the spindle microtubules break down, and the nuclear membrane reforms.Cytokinesis (Not a separate phase)Cytokinesis occurs at the end of the cycle, but is not actually a phase. This step either occurs during telophase or never occurs at all, in which case the cell fails to divide. In cytokinesis, the cytoplasm divides into two.
Where does mitosis take place in the human cell?
Most of the activity occurs in the middle of the cell itself.
Why mitosis has to come before cytokinesis in the cell cycle?
The most probable solution is that Mitosis requires alot of energy as well as a lot of nutrients to go through the process. Since Interphase is the beginning stage, the G1, S and G2 phases come into play and help create nutrients and energy.
If you examine a population of intestinal epithelial cells under a microscope most of the cells would appear in what phase of the cell cycle?
Most of the intestinal epithelial cells would likely be in the G1 phase of the cell cycle, as they are constantly renewing and dividing to maintain the integrity of the intestinal lining.
How long does it take cells to cycle on an onion root tip?
Onion root tip cells generally cycle through the cell cycle in about 24 hours. This means that all the stages of the cell cycle, including interphase, mitosis, and cytokinesis, occur within this time frame. This rapid cell cycle allows for continuous growth and development of the onion root tip.
Which stages make up interphase of the cell cycle?
Interphase{G1 (cell growth), S (DNA is copied), G2 (growth and preparation for cell division)}, Cell Division {mitosis and cytokinesis} False
The longest stage of cell division?
Prophase is the longest stage of cell division, since so many things have to happen in order for other stages to proceed. However, if you consider the whole cell cycle, then the answer is undoubtedly interphase, which takes up most of the cell cycle.
What happens when mitosis stops?
Yes, certain cells such as your brain and skeletal muscle cells stop cell division at or around the time of birth and are arrested in a phase of interphase called G0where they no longer divide.
