colchicine is used to stop cell cycle during metaphase. In chromosome karyotype analysis, it is used.

Which phase comes immediately before the M phase?

Interphase


How many stages are there in mitosis?

It's best to visualize this with pictures of the various phases, so I will share a link with you to go to The Biology Project, a trusted website for understanding the cell cycle (see related links at the bottom of the answer). Mitosis is a dynamic process, so when it is happening, it is difficult to see where one phase starts and the other stops, but if you were to film it and then slow down the film, you could see certain identifiable activities that would allow you to draw a line across the film strip to say one phase has ended and the other started. Most people would draw lines to make the following phases: prophase, prometaphase, metaphase, anaphase, and telophase. Some people don't include the prometaphase as a separate stage, or they call it late prophase. Before cells go into prophase, the first phase of mitosis, they are in a cell cycle stage called interphase. This is not officially a phase of mitosis, but it is helpful to think about what the stages of the cell cycle are: the quiescent (quiet) stage, also known as Gap 0; the interphase, including stages Gap 1 (cells increase in size, and prepare for DNA synthesis), Synthesis (DNA replication occurs), Gap 2 (checkpoint where cell continues to grow and further prepares for mitosis); the mitotic stage, or cell division stage. Cell division entails nuclear division (mitosis) and cytokinesis (division of the cytoplasm). So, to fully answer your question, I think the most accurate answer is that there are 5 well-recognized phases in mitosis, and some people might also include the two bookends, interphase (before mitosis) and cytokinesis (after mitosis). I think it is best to know what happens in each stage, and what distinguishes one stage from the other, but that is best done with pictures, so I do recommend looking at the Biology Project website.


What is it called when cell growth and division stops because the cells have run out of room?

Cell growth and division stops when cells become crowded or reach a certain density, which is known as contact inhibition. This mechanism helps control tissue growth and prevent overcrowding of cells.


What is the human life cycle called?

The stages of a cell's life cycle are also known as cell cycle stages. They are gap phase 1 (G1), synthesis (S), gap phase 2 (G2), mitosis (M), and cytokinesis . G1, S, and G2 are collectively known as interphase. Mitoses is further broken down into prophase, metaphase, anaphase, and telophase. Sometimes a cell will enter a G0 sometime after G1. This is a stage where cell growth stops. However, it is possible for the cell to reenter G1 and finished the process of division.


Which stage of cell cycle varies most in length?

There isn't a way (yet) to defined the lengths of stages in the cell cycle. One reason is because the cell cycle makes several stops/checkpoints. The G2 stage has a checkpoint/stop if DNA has not finished replicating and this will prevent the start of the M stage before completion of the S stage. Another cell cycle checkpoint occurs during the M (mitotic) stage. The cell cycle stops if the chromosomes are not going to be distributed correctly to the daughter cells. Damage to the DNA can also stop the cell cycle at the G1 stage and if damage is found then DNA repairs will start but if any kind of problem is not possible to fix than cell will automatically begin apoptosis "a.k.a. cell suicide". For adult mammalian cells, interphase "which includes three stages G1, S, and G2" lasts for about 20 hours and accounts for 90% of the cell cycle and yet embryonic cells can complete the entire cell cycle in just a few hours..

What activity happens during the M phase?

During the M phase of the cell cycle, cell division occurs. This includes mitosis, where the nucleus divides, and cytokinesis, where the cytoplasm divides, resulting in the formation of two daughter cells. The M phase is a crucial stage for ensuring accurate distribution of genetic material to the daughter cells.


Which phase comes immediately before the M phase?

Interphase


What stops cell division?

Cell division starts when there is an imbalance in the level of protoplasm and nucleoplasm IT STOPS WHEN there is uniformity formed again in the levels of nuclear and protoplasm

What happens to cell division rate as you age?

The cell division rate slows down and evetually stops.

Why is colchisine used in karyotypic determination?

Colchicine causes microtubules to depolymerise. During cell division at the metaphase stage condensed chromosomes line up and are then pulled apart to either pole by microtubules. Hence adding colchicine to a cell culture stops cells completing mitosis. This is useful as a means of accumulating metaphases in the culture before harvesting. Typically colchicine (or the less toxic colcemid) is added about 30mins to 1 hour before harvesting, varying depending on cell type, species etc.
