Question

i need it super now!!!!

please help me...

i need it as soon as possible...

thank you!!!:))

Answer 1

As another answerer has indicated, it depends on the part of the cell that is lost and, to a degree, how much is lost.  For example, losing a single ribosome is not a life or death scenario for a cell because there are many ribosomes in the cell.  However, if the cell membrane was lost, which is a part of the cell, the cell could not exist because the membrane helps to hold in all of the organelles of the cell, protect the internal contents from the external environment, and creates a barrier to regulate the concentration of various ions and proteins inside to cell.  In a large part, what happens to the cell if it looses one of its parts depends on the exact part.  Often, however, losing a part of the gene leads to either necrosis (cell death), programmed cell death (apoptosis) or cancer.  Necrosis generally results from the cells inability to function (think, for example, if the mitochondria was suddenly lost, the cell could not make enough energy to survive).  Apoptosis results from various internal and external cell signals, but if an anti-apoptotic gene or protein were lost, you can imagine how apoptosis could occur more easily.  The loss of certain cell cycle checkpoint genes or their protein products can lead to cancer.  In fact, a large percentage of cancers result from mutations in the tumor suppressor gene that encodes for the protein p53, rendering it inactive.

Answer 2

most of the time - die

-  or mutate

depends which part it lost

Answer 3

I am guessing it does not work anymore

Thousands of cells get replaced in the body everyday
