having or showing a disposition to avoid exertion; slothful: an indolent person. 2. Pathology. causing little or no pain; inactive or relatively benign: an indolent ulcer that is not painful and is slow to heal.
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3' end, and the phosphate is the 5' end of each nucleiotide.
Nucleotide-Polymer Formation. DNA and RNA polymers are constructed by forming phosphodiester bonds between nucleotides. In this arrangement, a phosphate group acts as a bridge between the 5â² position of one sugar and the 3â² position of the next.This arrangement is called the sugar-phosphate backbone of DNA or RNA; the bases hang off to the side.enetic chains acid individual nucleotides. Nucleotides are the building blocks of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Individual nucleotide monomers (single units) are linked together to form polymers, or long chains.
