Nucleotides are linked together by the formation of a phosphodiester bond which is formed between the 3' -OH group of one sugar molecule, and the 5' phosphate group on the adjacent sugar molecule.
This results in a loss of a molecule of water, making this a condensation reaction, also called a dehydration synthesis. What covalent bond links nucleotides together? Chemistry Bonding Basics Covalent Bonding. Jul 2, Deoxyribose is the pentose sugar found in this type of polynucleotide, hence its name D eoxyribo n ucleic A cid, or DNA. The nitrogenous bases found in DNA are, adenine, guanine, cytosine and thymine. DNA molecules have two polynucleotide chains, held together in a ladderlike structure.
The sugar phosphate backbones of the two chains run parallel to each other in opposite directions. Each "rung" of the ladder is a pair of nitrogenous bases, one purine and one pyrimidine extending into the center of the molecule.
The pairing of these bases is always adenine with thymine A - T and guanine with cytosine G - C. The sugar-phosphate backbones of the two polynucleotide chains coil around one another making the "ladder" into a spiral "staircase". This superstructure is known as a "double helix".
DNA acts as the store of genetic information.
