Question

What is the function of the nucleus?
1. It controls only the division of cells
2. It controls only certain specific functions
3. It controls all the activities of a cell 
4. It has no specific function

Answer 1

Correct Answer - Option 3 : It controls all the activities of a cell 

The correct answer is It controls all the activities of a cell.

• The nucleus is a pivotal organelle responsible to regulate almost all forms of cellular activities.
• Mostly, every type of cell that exists is categorized on the basis of the absence or presence of the nucleus within its cell (categorized either as a prokaryotic or eukaryotic cell)
• Following are the important nucleus function:
  • It contains the cell’s hereditary information and controls the cell’s growth and reproduction.
  • The nucleus has been clearly explained as a membrane-bound structure that comprises the genetic material of a cell.
  • It is not just a storage compartment for DNA but also happens to be the home of some important cellular processes.
  • First and foremost, it is possible to duplicate one’s DNA in the nucleus. This process has been named DNA Replication and produces an identical copy of the DNA.
  • Producing two identical copies of the body or host is the first step in cell division, where every new cell will get its own set of instructions.
  • Secondly, the nucleus is the site of transcription. Transcription creates different types of RNA from DNA. Transcription would be a lot like creating copies of individual pages of the human body’s instructions which may be moved out and read by the rest of the cell.
  • The central rule of biology states that DNA is copied into RNA, and then proteins.
