DNApolymer

DNApolymer refers to a strand of deoxyribonucleic acid, a molecule essential for life. It is a long chain of repeating units called nucleotides. Each nucleotide consists of three parts: a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), guanine (G), cytosine (C), or thymine (T). The phosphate group of one nucleotide links to the sugar of the next, forming a strong sugar-phosphate backbone. The nitrogenous bases project inwards from this backbone.

DNA polymers typically exist as a double helix, where two such strands wind around each other. The two strands are held together by hydrogen bonds between complementary bases: adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). This specific base pairing is crucial for DNA's ability to store and replicate genetic information. The sequence of these bases along the DNApolymer dictates the genetic code, which directs the synthesis of proteins and carries hereditary information from one generation to the next. DNApolymer is the fundamental building block of chromosomes found within the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.
