DNA (deoxyribonucleic acid) is a polynucleotide made of monomers. each monomer consists of a pentose sugar, a nitrogen base,and a phosphate group. the monomers link together by phosphodiester bonds forming a single strand of DNA. Each two DNA strands link together by hydrogen bonds according to base pairing forming the double helix of DNA.
DNA is the abbreviation for DeoxyriboNucleic acids. DNA usually takes active roles during human formation because it contains genetic information that can be passed from one generation to another. The reason why some traits in your family which were very visible in the older generations are still being noticed in the present generation is due to DNA because it acts in such a way that it replicates copies of itself. It does this by forming a new strand so that each new cell can have the genetic composition of the old cell. Since DNA can be found in the nucleus of each cell, it helps in regulating and coordinating the metabolic process of the cell and the development of organisms. Genetic information is stored as codes through the four bases in DNA, the codes are Guanine, Thymine, Cytosine, Adenine. They ensure that hereditary materials are passed from parents to their children
DNA is the well-known set of initials that stands for deoxyribonucleic acid. DNA is a chemical made up of two long molecules, arranged in a spiral, the double-helix structure that is one of the most exciting discoveries of our era. Every cell's nucleus contains DNA carrying genetic information. The DNA has all the instructions that a living organism needs to grow, reproduce and function. In a cell nucleus, DNA is arranged into coiled strands called chromosomes. One half is inherited from the father and one half from the mother.
(That's fair!) Every human has unique DNA and one of the amazing results of the discovery is that forensic scientists can collect human cells left at a crime scene, whether blood, saliva or hair, extract DNA from the cells, analyse it and make a DNA profile to check against a database of other profiles.
DNA is the abbreviation for Deoxyribonucleic acid - quite a mouthful to remember and pronounce, so few do! It is a molecule, a thread of nucleotides that form themselves into a pair of chains shaped like a double helix. It was the discovery of this that made the modest Watson and Click famous in 1953.
The helix is attached to a sugar-phosphate backbone and contains the essence or instruction for the development of a being, human or animal and is passed on by the parents to the child. It determines how an organism will develop, reproduce, and live. It is in every cell.

The meaning of DNA is deoxyribonucleic acid. If you are not yet familiar with what this is, this is known to be something that will self-replicate to ensure that all of the cells are uniform throughout the body. This carries genetic information that can be passed on from one generation to another.
It is because of DNA why family members look similar to each other. Similar DNA is being passed on and there may just be a few changes here and there. It can be problematic when DNA stops replicating properly, this might mean that some of the cells may become problematic.
