A DNA molecule consists of 4 different nucleotides. Each nucleotide consists of 3 components. A phosphate group, deoxyribose sugar, and a nitrogenous base. The 4 different nitrogenous bases (Adenine, ...
The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base ... RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and ...
and several nitrogen-containing bases. Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA ...
