DNA serves two important cellular functions: It is the genetic material passed from parent to offspring and it serves as the information to direct and regulate the construction of the proteins necessary for the cell to perform all of its functions.
DNA serves as the genetic material in cells, providing the instructions needed for the development, growth, and functioning of living organisms. It also carries hereditary information from one generation to the next through the process of replication and cell division.
"Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
Chemically, DNA is a long polymer of simple units called nucleotides, with a backbone made of sugars and phosphate groups joined by ester bonds. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription. Most of these RNA molecules are used to synthesize proteins, but others are used directly in structures such as ribosomes and spliceosomes.
Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms such as animals, plants, and fungi store their DNA inside the cell nucleus, while in prokaryotes such as bacteria it is found in the cell's cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins and thereby control which genes are transcribed." This definition is taken from Wikipedia.
carrying genetic information
DNA controls the production of certain proteins in the cell. Different DNA codes make different proteins. Proteins made in the cell bond together to make amino acids.
DNA carries genetic information from one generation to the other.
Its gene expression is dependent on synthesis of proteins.
The functions of DNA are vital for inheritance, coding for proteins and the genetic blueprint of life.

What is the DNA function?
DNA functions as the storage of genetic information in cells. It carries the instructions needed for the development, functioning, growth, and reproduction of organisms. DNA also plays a crucial role in protein synthesis and gene expression.
What is the difference between coding DNA and junk DNA?
Coding DNA refers to the portion of DNA that contains instructions for making proteins, while junk DNA, also known as non-coding DNA, does not encode proteins. Junk DNA plays roles in regulating gene expression, chromosome structure, and other cellular functions, although its exact functions are still being explored.
What does a plant cell DNA do?
DNA controls the actions of the plant cell. This includes the processes of the plant cell and all of its functions.
What is the cell structure that contains DNA and controls the functions of the cell called?
cell nucleus
What is the large structure that contains the cell's DNA is the?
The large structure that contains the cell's DNA is the nucleus. It acts as the control center of the cell and houses the genetic material that dictates the cell's functions and characteristics.
How does DNA talk to you?
DNA directs all of your cell functions.
State the two functions of DNA.?
The two functions of DNA are to store genetic information and transmit/express genetic information
What is a molecule that carries the instructions for growth and functions of a cell?
DNA
Where do all the functions of the cell occur?
dna
Functions of DNA?
its like a genetic code
What is DNA ligase functions?
Ligase joins together the Okazaki fragments into a continuous strand of DNA.
What is the DNA function?
DNA functions as the storage of genetic information in cells. It carries the instructions needed for the development, functioning, growth, and reproduction of organisms. DNA also plays a crucial role in protein synthesis and gene expression.
What three things happen when cells grow?
1. It grows/matures 2. Carries out it's regular functions 3. Produces DNA
What is the main functions of nucleic acids are to?
To create DNA sequence
What are two functions of a virsus's protein coat?
Dna,rna
What Stores DNA and controls Functions of a cell?
The nucleus stores DNA in the form of chromosomes and acts as the control center of the cell, regulating its functions. Within the nucleus, DNA is transcribed into RNA, which is then used as a template for protein synthesis in the cytoplasm.
What is the difference between coding DNA and junk DNA?
Coding DNA refers to the portion of DNA that contains instructions for making proteins, while junk DNA, also known as non-coding DNA, does not encode proteins. Junk DNA plays roles in regulating gene expression, chromosome structure, and other cellular functions, although its exact functions are still being explored.
