The Incredible World of Cell Biology

What is the main function of the cell nucleus?

A. Synthesis of proteins

B. Storage of genetic material

C. Energy production

D. Waste elimination

Answer:

B. Storage of genetic material

The cell nucleus is a membrane-bound organelle that serves as the control center of the cell. It is where the genetic material, DNA, is housed and protected. The main function of the cell nucleus is to store the genetic material and regulate gene expression. This DNA contains the instructions for making proteins and controlling the activities of the cell.

Inside the nucleus, there is a structure called the nucleolus, which is responsible for producing ribosomes. It plays a key role in protein synthesis by providing the necessary machinery for translating the genetic code into proteins.

Overall, the cell nucleus is crucial for the proper functioning and growth of the cell, making it a vital organelle in cell biology.
