Detailed explanation-1: -Nucleic acids are biopolymers, macromolecules, essential to all known forms of life. They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Detailed explanation-2: -Nucleic acids are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Detailed explanation-3: -The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.
Detailed explanation-4: -Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain. In DNA, the nucleotides are referred to in shorthand as A, C, T, and G. In RNA, the nucleotides are A, C, U, and G.
Detailed explanation-5: -The biomass of a cell (the organic contents, excluding water and inorganic salts) is composed of 3 types of macromolecules plus lipids. The 3 types of macromolecules (very large molecules) are polysaccharides, nucleic acids (DNA and RNA), and proteins.
