What is a nucleic acid composed of?
Generally, a phosphate group, a deoxiribose sugar and a nitrogenous base.
DNA and RNA are nucleic acids. DNA is deoxyribonucleic acid, and RNA is ribonucleic acid. Nucleic acids are composed of chains of nucleotides, each of which is composed of a five-carbon sugar (deoxyribose or ribose), a nitrogen base, and a phosphate group. Nucleic acids make up the genetic code necessary for life.
A nucleic acid is a macromolecule composed of chains of monomeric nucleotides. In biochemistry these molecules carry genetic information or form structures within cells. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). 2 examples of nucleic acids as said before are DNA and RNA.
