What would happen in case a cell gets damaged?
When cells are damaged by harmful factors (such as injury or toxic chemicals), they usually “spill their guts” as they die. Because the damaged cell’s plasma membrane can no longer control the passage of ions and water, the cell swells up, and its contents leak out through holes in the plasma membrane.
What will happen to a cell if its nucleus is removed Why?
If the nucleus of a cell is removed, then the cell will die. This is because the nucleus of a cell controls all the metabolic activities in a cell, and if it is not present, then the metabolic functioning of the cell will stop and its protoplasm will dry up ultimately, causing cell death.
Can you repair damaged DNA?
Most damage to DNA is repaired by removal of the damaged bases followed by resynthesis of the excised region. Some lesions in DNA, however, can be repaired by direct reversal of the damage, which may be a more efficient way of dealing with specific types of DNA damage that occur frequently.
What will happen if the nucleus of amoeba is removed?
When the nucleus is removed from an amoeba, there is a 70 p.c. reduction in respiration, locomotion becomes very sluggish and infrequent, food is not digested and the amoeba dies after about seven days (Clark, 1942).
Can a cell survive if its nucleus is taken out?
It is the brain of the cell and controls most of its functions. If the nucleus is removed from the cell then the cell will not be able to function properly, it will not be able to grow. All the metabolic functioning of the cell will stop. Gradually, the cell may die.
Can a cell survive without nucleus?
Nucleus is the brain of the cell and controls most of its functions. Thus without a nucleus, an animal cell or eukaryotic cell will die. Without a nucleus, the cell will not know what to do and there would be no cell division. Protein synthesis would either cease or incorrect proteins would be formed.
Which vitamin helps with DNA repair?
Vitamin C supplementation was potentially beneficial, because an increase in DNA repair incision capacity was observed, which was not seen in well-nourished subjects.
