Helloeww guys.....
Write five differences between the malignant cancer cells and the normal cells !
Answers
normal cells: Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, new cells are no longer produced when there are enough cells present to fill the hole (when the repair work is done).
malignant cancer cells: cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.
( additional)
Each gene in the body carries a blueprint that codes for a different protein. Some of these proteins are growth factors—chemicals that tell cells to grow and divide. If the gene that codes for one of these proteins is stuck in the “on” position by a mutation (an oncogene) the growth factor proteins continue to be produced. In response, the cells continue to grow.
normal cells: Normal cells respond to signals sent from other nearby cells that say, essentially, “you’ve reached your boundary.”
malignant cancer cells: Cancer cells don’t interact with other cells as normal cells do
normal cells: Normal cells are either repaired or die (undergo apoptosis) when they are damaged or get old.
malignant cancer cells: Cancer cells are either not repaired or do not undergo apoptosis.
Under a microscope, normal cells and cancer cells may look quite different. In contrast to normal cells, cancer cells often exhibit much more variability in cell size—some are larger than normal and some are smaller than normal.
hope it helps you :)
Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.
