DNA: Definition, Structure & Discovery DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes, which in the language of the cell, tells cells how to make proteins.he order of these bases is what determines DNA's instructions, or genetic code.

Is DNA made of protein? Best Answer: Definitely not. DNA itself is a nucleic acid which is made up of nucleotides. The latter are made of three parts 1. any one purine or pyrimidine base (there four kinds of these, two of each) 2. one deoxyribose sugar 3. one phosphate group. There is not a trace of protein or even amino acid in it. DNA in the nucleus is supported by proteins but they are just support structures and not part of it.

- A closer look at the chemical structure of DNA includes the four nitrogenous bases Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). DNA also includes sugars and phosphate groups that make the phosphate-deoxyribose backbone. If you think of the structure of DNA as a twisted ladder, the rungs of the ladder are made from the nitrogenous bases. These bases pair up to make each step of the ladder.

What is DNA? DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. The National Human Genome Research Institute fact sheet Deoxyribonucleic Acid (DNA) provides an introduction to this molecule. Information about the genetic code and the structure of the DNA double helix is available from GeneEd. StatedClearly offers a video introduction to DNA and how it works. The New Genetics, a publication of the National Institute of General Medical Sciences, discusses the structure of DNA and how it was discovered. A basic explanation and illustration of DNA can be found on Arizona State University's Ask a Biologist website.

Biology for Kids DNA is a long thin molecule made up of something called nucleotides. There are four different types of nucleotides: adenine, thymine, cytosine, and guanine. Holding the nucleotides together is a backbone made of phosphate and deoxyribose. The nucleotides are sometimes referred to as bases.

Understanding the Double Helix Structure of DNA Double Helix. Definition: In biology, double helix is a term used to describe the structure of DNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of spiral staircase. DNA is a nucleic acid composed of nitrogenous bases (adenine, cytosine, guanine and thymine), a five-carbon sugar (deoxyribose), and phosphate molecules.

What is DNA? DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. 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.ucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.

Concept 19 The DNA molecule is shaped like a twisted ladder. Concept 19 The DNA molecule is shaped like a twisted ladder. Earlier work had shown that DNA is composed of building blocks called nucleotides consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogen bases — adenine (A), thymine (T), guanine (G), and cytosine (C). Phosphates and sugars of adjacent nucleotides link to form a long polymer. Other key experiments showed that the ratios of A-to-T and G-to-C are constant in all living things. X-ray crystallography provided the final clue that the DNA molecule is a double helix, shaped like a twisted ladder. In 1953, the race to determine how these pieces fit together in a three-dimensional structure was won by James Watson and Francis Crick at the Cavendish Laboratory in Cambridge, England.

The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
