Base pairs (Adenine--Thymine Cytosine---Guanine)
Phosphate
Deoxyribose
Adenine and Thymine form 2 hydrogen bonds together when paired and each have a sugar (deoxyribose) and a phosphate group attached to them. All nucleic acid nucleotides' base pairs are directly connected to the sugar and the phosphate connects two sugars to form the helix at a 10 base pair nucleotide per every 360 degree rotation of DNA. Cytosine and Guanine form 3 hydrogen bonds and follow the same prinicples otherwise.

DNA is deoxyribonucleic acid. It's a double helix (sort of a spiral ladder) in the nucleus (powerhouse, controls everything) of a cell. It contains all the genetic codes for a person. It's two chromosomes that have come together (1 from each parent). Biology and Human Anatomy are actually very interesting topics. Take some classes.

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living organisms. All living things contain DNA, with the exception of some viruses with RNA genomes. The main role of DNA in the cell is the long term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information.
In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria, the DNA is in the cell's cytoplasm. Unlike enzymes, DNA does not act directly on other molecules; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe it into protein. In chromosomes, chromatin proteins such as histones compact and organize DNA, as well as helping control its interactions with other proteins in the nucleus.
DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. These RNA copies can then be used to direct protein synthesis, but they can also be used directly as parts of ribosomes or spliceosomes.
