What else can I help you with?
What must happen before both mitosis and meiosis begin?
believe it or not, mitosis always takes place in the cell; it never stops, even for a fraction of a second! However, there has been a stage called Interphase, which was once incorrectly termed as the Resting Phase of a cell. Scientists have proved that this is not so, for in this stage, the cell engages in different activities to prepare for the next cell division, such as: replication of the DNA, replication of centrioles, formation of new cellular organelles, chromosomes appear as long chromatic threads swollen at intervals into visible chromatic granules, and lastly, the cell synthesizes and stores enough energy, ready for the division! Have I answered your question? -B.C.O :-)
Why cant you see the chromosomes during interphase?
In interphase, the DNA has just replicated and exists as loosely coiled chromatins. They have not yet condensed enough to be the form of a chromosome. In the next stage, prophase, the DNA will shorten and condense into the easily recognizable chromosome structure.
What is once a year called?
Once a year is called an annual event.
What has to happen before a cell divides?
It will go through mitosis and interphase. During interphase the cell grows, replicates DNA and prepares for cell division. then during mitosis it has to through four stages. prophase,metaphase,anphase,and telophase. During these four stages chromosomes duplicate, nucleus begins to divide, chromatids attach to the spindle fibers, chromatids separate and begin to move opposite ends of the cell, two nucei form, and finally the cell membrane moves inward to create two identical cells-each with it's own nucleus with identical chromosomes.
Does the cell cycle have a beginning and an end?
The cell cycle starts at Interphase where the cell works and grows. It stays in interphase for 90% of the total time of the cell cycle. The end of the cell cycle is Mitosis and Cytokinesis. Mitosis is the process that divides the nuclear material. Cytokinesis is the process that divides the cytoplasm and the rest of the organelles in half.Hope i helped.
What is the period of cell life when cell doesn't divide?
Interphase is:1. "The metabolic stage in the cell cycle during which the cell is not dividing."2. "The interval between two successive cell divisions, during which the chromosomes are not individually distinguishable. The long stage in the cell cycle between successive meioses."ok, im Alice. go on Ask.com, it is WAY better. or even Gogogle. Answer.com can be wrong. once i go a F on an assignment that i got my answers from here. good luck, goodbye, best wishesAlice
What is the g0 of interphase?
The G0 phase of the cell cycle is a resting phase where cells are not actively dividing. Cells in G0 have exited the cell cycle and are not preparing to divide. They may re-enter the cell cycle if appropriate signals stimulate them to do so.
Does meiosis go through interphase more than once?
No, meiosis only goes through interphase once, before entering the first meiotic division (meiosis I). Interphase consists of G1, S, and G2 phases where DNA is replicated and cells prepare for division.

Why do cells spend the most time in interphase?
Not all cells divide at the same rate, but that difference is only in the length of the interphase which can vary by up to years for some tissues. It is just that prophase, metaphase, anaphase and telophase are much less variable as the process has to complete (not stable stuck in the middle of dividing, see Larson).
How many times does DNA replicate in meiosis?
1 time only which is done during the only interphase in meiosis.
The first stage of a multi stage rocket is called what?
The first stage of a multi-stage rocket is called the booster stage. It is responsible for providing the initial thrust needed to lift the rocket off the ground and begin the ascent to space. Once its fuel is expended, it separates from the rocket to reduce weight and allow the next stage to continue the journey.

Describes the symptoms of HIV infection in the asymptomatic stage?
In the earliest stage of an HIV infection the symptoms are identical to the flu, but once it enters the asymptomatic stage there are no symptoms until it becomes active again and the immune system begins to fail. That is why it is called the asymptomatic stage (i.e. without symptoms).
Why not easy to observe individual chromosomes during the interphase?
coz in interphase, the chromatin threads are not yet condensed into what is called as chromosomes. they are thread like structures, and make a network called chromatin network. chromatin threads only begin to condense into thicker structures called chromosomes once the process of cell division actually begins
What phase of the cells cycle is typically the longest phase?
Interphase is the longest phase of the cell cycle because it's the phase between divisions. It involves G1, S, G2, and G0 phase where the cell goes through growth after its division and then preperation to go through mitosis again.
When do chromosomes replicate during meiosis?
Chromosomes replicate during the S phase of interphase, before meiosis begins. This ensures that each chromosome consists of two sister chromatids, which are then separated during the meiotic divisions to produce haploid cells.
