Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases ... much like a ladder with sugar-phosphate side supports and base-pair rungs.

Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical ...

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, ...
