Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also know as the cell's command center,thus it controls the activity of the cells
Explanation:
- The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.

Therapeutic cloning is the
process of creating multiple copies of a cell to treat a disease. In this type of cloning, the nucleus of a
cell, such as a skin cell, is inserted into a fertilized egg whose nucleus has
been removed. The nucleated egg begins to divide repeatedly to form a
blastocyst. Stem cells are then extracted from the blastocyst and they are used
to grow cells that are a perfect genetic match for the patient. The cells
created through therapeutic cloning can then be transplanted into the patient
to treat a disease from which the patient suffers.
