WebDNA and RNA are comprised of monomers that scientists call nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Three components comprise each nucleotide: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group (Figure 3.31). Each nitrogenous base in a nucleotide is attached to a … WebFeb 25, 2024 · Sugar is one of the fundamental parts of DNA.

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.
