is mitosis constantly occurring in the cell ?

Answer 1

No. The cell first has to go through Interphase. In interphase it will start in Gap 1 phase. In gap 1, the cell will grow. After that, the cell will decide if it should destroy itself (if it's DNA is too damaged), cells around it will tell it to destroy itself (if the cell is unneeded), or it will be completely healthy, but just stop at the point where it is, because it is fully grown and mature (common in adults), for example, neuron cells in our brain. After that point, cells can continue through Interphase and then mitosis. However, mitosis only takes place in certain cells. A growing zygote, baby, and child will have mitosis occurring in many of its body cells. However, in all humans, a common example is our skin. When you get a cut, new skin is formed on top, and you are healed. This is because the skin cells undergo mitosis. Normally skin cells won't randomly undergo mitosis because imagine if you did! Your skin will keep growing and growing and you will be very flabby. Instead, when the body senses a need, it will allow mitosis to occur. Another important example is the regeneration of our blood cells. Red blood cells undergo mitosis to regenerate constantly.

Answer 2

mitosis takes place because of fact the organism desires the hot cells to proceed existence. The strategies in touch in mitosis are basically dimly understood in spite of the undeniable fact that that's usual that out of control mitosis = maximum cancers. Micro-biology rather exhibits us how plenty we don't understand. merely the actuality for you to use "mitosis" in a sentence tells me you have an interest, pursue it!

Answer 3

Only in certain tissues, like the hair follicle and gut lining. The heart cells and brain cells stop dividing when the body is fully grown.

Answer 4

No it stops for a coffee before getting into it again :o)

Answer 5

yes. cells are always dividing, replacing cells that have died.
