The nucleus is an important part of eukaryotic cells, playing several key roles:
Storing Genetic Information: The nucleus holds about 2 meters of DNA in human cells, which is organized into 23 pairs of chromosomes.
Controlling Genes: The nucleus helps control how genes work. About 98% of our DNA doesn’t code for proteins, but it still influences how our genes are expressed and managed.
Making Ribosomes: Inside the nucleus is a part called the nucleolus. This is where ribosomes are made. Eukaryotic cells can create thousands of ribosomes every minute!
Helping Cells Divide: When cells split during a process called mitosis, the nucleus makes sure that the genetic material is copied accurately and shared evenly. This is important for growth and healing in the body.
Protecting DNA: The nuclear envelope is a double layer around the nucleus. It protects the DNA from other activities in the cell, showing just how important the nucleus is for keeping the cell healthy and functioning well.
