so be stupid and look in your text books
your probably talking about the nucleus containing DNA which tells the cell what to be like and do. the function of the cell is programmed into its dna.
The nucleus's main function is to hold the DNA. Prokaryotic cells do have the DNA but it is not surrounded by a membrane that separates it from the rest of the cell so the DNA just floats around in the region called nucleiod instead of being confined inside a nucleus.
Nucleus: The control center for all the cells activities. It contains the chromosomes (DNA)
The structure in the nucleus that serves as the storehouse for information needed by the cell to function is the chromatin. Chromatin consists of DNA and proteins, and it contains the genetic instructions for synthesizing various molecules and proteins required for cell activities.
nucleus
Most bacteria don't have a nucleus and they function using free floating DNA within the cell.
Eukaryotic cells have DNA bound in a nucleus. The nucleus of a eukaryotic cell serves as the control center for the cell, housing the genetic material (DNA) that contains instructions for cell function and replication.
the function is it helps protect the DNA of the nucleus it also can make the cell smarter
It separates the DNA from the rest of the cell.The nuclear membrane protects the nucleus.
The nucleus is the "control center" of the cell. It tells the cell how to function and chromosome development. Chromosomes contain the genetic or hereditary instructions. Chromosomes are both composed of nucleic acids and protein. The nucleic acid in protein is called deoxyribonucleic acid (DNA). DNA is stored in the Nucleus. It is not allowed to leave, for it to be used it must be copied. Short single stranded copies of one of the two DNA strands in the nucleus are made from ribonucleic acid (RNA). these copies represent detailed messages that can be transported out of the nucleus. (as mRNA)
The nucleus is responsible for controlling cell function. It contains the cell's DNA, which holds the instructions for making proteins and determining the cell's characteristics. The nucleus regulates protein synthesis and coordinates the cell's activities.
The special function of DNA in the nucleus is to store genetic information that determines an organism's characteristics. This information is used to direct cellular activities and protein synthesis through transcription and translation processes. DNA also undergoes replication to ensure accurate transfer of genetic material during cell division.
