Deoxyribose Nucleic Asid

DNA strand is made from alternating phospate and sugar residues. Thesre two strands run in opposite directions to each other and therefore antiparallel Attached to each sugar is one of four types of molecules called bases, The sugar in DNA is 2-deoxyribose which is apentose sugar searches of DNA into the related nuclear acid RNA in aproesss sugsrs are joined to phospate groups that from phosphodiester bonds between the third and forth carbon atoms adjacent sugar rings.

DNA is a long polymer made from repeating units called nucleotides. The DNA is chain is 20-26 angstroms wide. DNA polymers can be very large molecules containing millions of nucleotides chemically with backbones made of sugars and phospates groups joined by ester bonds these on formation is using the genetic code. Phospate groups are joined by ester bonds. In living organisms.

DNA does not usually exist as a single molecule but it exists as a pair of molecules that are held tightly together. These two long strands and entwine like vines, in the shape a double helix. which holds chain together and a base which interacts with the other DNA strand in the helix. A base linked to a sugar is nucleotide. If multiple nucleotide are linked to together as in DNA this polymer is known as a polynucleiotide.
