DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
DNA is made up of two long chains of nucleotides, which are the building blocks of DNA. These chains are twisted together in a double helix, and the sequence of nucleotides ineach chain forms the genetic code. One of the most fascinating aspects of DNA is its role in inheritance. DNA ...

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 determ...
and one nucleotide unit is 3.3 (0.33 nm) long. [5] Although each individual repeating unit is very small, DNA polymers can be very large molecules containing millions of nucleotides. For instance, the largest human chromosome, chromosome number 1, is approximately 220 million bas...
The general structure of a section of DNADeoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. DNA is a long polymer of nucleotides ...
DNA is made up of two nucleotide strands. The nucleotides are connected together bycovalentbonds within each strand. The sugar of one nucleotide forms a covalent bond with the phosphate group of another. The two strands themselves are connected by hydrogen bonds. The hydrogen bonds are found betw...
It is often referred to as the "blueprint of life" because it containsthe information needed to build and maintain an organism. DNA is composed of two long strands that coil around each other to form a double helix structure. Each strand is made up of a series of nucleotides, which are...
DNA is a polymer of nucleotides, each of which is made up of a nitrogenous base, a deoxyribose sugar, and a phosphate group. In a double stranded DNA molecule, the nitrogenous bases which include the purines; adenine (A) and guanine (G), and the pyrimidines; cytosine (C) and thymine...
