Nucleic acid | Definition, Function, Structure, & Types
网页2024年9月9日 · What is the basic structure of a nucleic acid? Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides . Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
Nucleic acid structure - Wikipedia
网页Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.
Nucleic acid - Wikipedia
网页Nucleic acids are large biomolecules that are crucial in all cells and viruses. [ 1 ] 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).

网页2024年6月29日 · The nucleic acids consist of two major macromolecules, Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that carry the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and viruses.
Understanding biochemistry: structure and function of nucleic acids
网页2019年10月11日 · Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
