Which of the following describes a genetic mutation that results in uncontrolled division of a single cell within the body?
Cancer
Gene therapy
Stem cell
Translation
The Correct Answer is A
A genetic mutation that results in the uncontrolled division of a single cell within the body describes cancer. Cancer is a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
The other options are not correct because they do not accurately describe a genetic mutation that results in the uncontrolled division of a single cell within the body. Gene therapy, stem cells, and translation are not processes that result in uncontrolled cell division.

Soap’s dual polar and nonpolar nature helps bond oil and water. Soap is an emulsifier, which means that it has both polar and nonpolar regions. The polar regions of soap molecules are attracted to water, while the nonpolar regions are attracted to oil and grease. This allows soap to bond with both water and oil, helping to remove dirt and grime from surfaces.
B. Soap’s acidity does not cause grime to precipitate into the water.
C. Soap does not have enzymatic action that helps to dissolve grime into small particles.
D. Soap’s texture does not physically scour grime off surfaces.
