The instructions for a cell to carry out its activities are stored in its DNA (deoxyribonucleic acid). DNA contains genes, which are specific sequences that code for proteins, the molecules that perform most cellular functions. These instructions are transcribed into messenger RNA (mRNA), which is then translated into proteins by ribosomes. This process enables the cell to respond to internal and external stimuli and maintain homeostasis.
The nucleus is the organelle that has DNA because the nucleus also has chromosomes which store directions that carry information that controls the cell's activities.
All cells store DNA and direct itself to do cell activities that it normally would do. The nucleus is what stores the DNA and directs cell activities, but it is not a cell. The nucleus is an organelle.
Cell activities are directed by the genetic information contained in the cell's DNA. This information is transcribed into RNA and translated into proteins, which then carry out specific functions within the cell. Various signaling molecules within the cell also play a role in coordinating and regulating these activities.
CHROMOSOMES! DNA consisting of nucleotides present in the chromosomes carries coded instructions for the cell's activities.
Mini cell phones can be purchased both online and in stores. Stores such as Amazon, WireFly, AT&T, HTC, eBay, and Best Buy carry miniature cell phones.

DNA is a nucleic acid that stores genetic information and controls cell activities.
A molecule of adenosine triphosphate (ATP) carries the chemical energy necessary for cell functions and life activities. It acts as a universal energy currency in cells, powering various processes like metabolism, growth, and movement.
The smallest unit that can carry on all activities of life in a cell is the cell itself. Cells are the basic structural and functional unit of all living organisms. Each cell is capable of performing essential functions such as metabolism, growth, and reproduction.
