Which cell structure contains DNA and controls the cells activities?
Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.
What is the structure that contains the DNA of the cell?
What controls the functions of a cell?
The nucleus is the control center of the cell that contains the chromosomes with their genetic material, DNA. The nucleus controls all cellular functions. Chromosomes are large molecules in the nucleus made up of DNA and protein.
What is the structure that contains DNA and directs the cell?
What are the cells instructions called?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
What organelle is called the powerhouse of a cell?
What types of cell have DNA?
There are two basic types of cells, prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material.
Does every cell have the same DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.
How do you explain DNA?
Deoxyribonucleic acid, or DNA, is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.
What is DNA and why is it important?
DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.
Is there life without DNA?
DNA is a fancy form of RNA. Some viruses and some bacteria have RNA instead of DNA for their coding material. There is no life without RNA. The RNA or DNA has two jobs, 1) to make an exact copy and 2) to make the proteins that make the body of the being.
Do viruses need energy?
So, viruses cannot reproduce by themselves. Next, all living things have metabolism. Viruses only need energy when they make copies of themselves, and they don’t need any energy at all when they are outside of a cell.
