WebMar 1, 2024 · Identify the sugar, phosphate, nitrogenous base, 5' and 3' carbons in a nucleotide and the key difference between DNA and RNA. Explain the structure of the double helix, including the role of hydrogen bonds and covalent (phosphodiester) bonds. Explain why the abundance of A is roughly equal to T and G is roughly equal to C in DNA. WebEach DNA strand is composed of nucleotides—units made up of a sugar (deoxyribose), a phosphate group, and a nitrogenous base. Each strand of DNA is a polynucleotide composed of units called nucleotides. A nucleotide has three components: a sugar molecule, a phosphate group, and a nitrogenous base.

WebThe sugar phosphate backbone is an important stuctural component of DNA. It consists of 5-carbon deoxyribose sugars and phosphate groups. These sugars are linked together by a phosphodiester bond, between carbon 4 of their chain, and a CH 2 group that is attached to a phosphate ion. WebThe sugars in the backbone. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The full name of DNA, deoxyribonucleic acid, gives you the name of the sugar present - deoxyribose.
