The nucleotide is the building block of two important macromolecules (nucleic acids) in the living organisms; that is, the DNA and RNA. Purines are derived from pyrimidines by addition of an imidazole group. For now, when we discuss nucleic acids you should assume we are discussing DNA rather than RNA, unless otherwise … • According to the Arrhenius definition, a compound should have a hydroxide anion and the ability to donate it as a hydroxide ion to be a base. Nucleic acid is composed of a phosphate group and a nitrogenous base, which are attached to a pentose sugar. Nitrogenous base is linked to first carbon. The nitrogenous base is a part of a nucleotide. Pyrimidines are heterocyclic amines with two nitrogen atoms in a six-member ring and include uracil, thymine, and cytosine. The nucleotide is a compound that is composed of three parts: a 5′ carbon pentose sugar molecule, nitrogenous base, and phosphate group. Nucleotide serves as the energy source and transducers of signals that are polymerized to form RNA or DNA. Those nucleotides, themselves comprising a number of components, bond together to form the double-helix first discovered by the scientists James Watson and Francis Crick in 1956. Strong bases are those that can completely ionize in an aqueous solution while a weak base is a compound that partially ionizes. Nitrogenous bases found in nucleotides are adenine, guanine, cytosine, thymine and uracil. The purine (adenine and guanine) and pyrimidine (cytosine, uracil, and thymine) are the nitrogenous bases. answered May 11, 2019 by Divyanshi (25.9k points) selected Jun 2, 2019 by Vikash Kumar . In the most common nucleotides the base is a derivative of purine or pyrimidine, and the sugar is the pentose (five-carbon sugar) deoxyribose or ribose. Condensation reaction. In this case, one to three phosphate groups can be attached to the 5′ carbon of the pentose sugar. Nucleotides can have up to three phosphate groups bonded to them, and they are referred to as monophosphate, diphosphates, and triphosphates respectively. Simply speaking, a nucleotide consists of sugar, a nitrogenous base, and phosphate groups that number one to three. Bronsted- Lowry defines a base as a substance that can accept a proton.
