Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in …

Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are classified as purines. The primary structure …

Each nucleotide monomer is built from three simple molecular parts: a sugar, a phosphate group, and a nucleobase. (Don’t confuse this use of “base” with the other one, which refers to a molecule that …

Jan 23, 2026 · DNA is made of nucleotides. A nucleotide has two components: a backbone, made from the sugar deoxyribose and phosphate groups, and nitrogenous bases, known as cytosine, thymine, …

The sugar-phosphate sections of DNA are often referred to as the ‘backbone’ of the DNA structure, while the base pairing is referred to as the ‘rungs’, like those of a rope ladder.

In summary, DNA’s structure is characterized by two anti-parallel strands wound around each other in a double helix. The sugar-phosphate backbone forms the structural framework on the outside, while …

Apr 28, 2024 · Explore nucleotides—the building blocks of DNA and RNA. Learn about their structure, types, and essential roles in genetic information storage and cellular processes.

Let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA and RNA are nucleotides, which are made up of …

Aug 31, 2023 · A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). These molecules consist of three …

Primary Structure of Nucleic Acids Nucleotides are joined together through the phosphate group of one nucleotide connecting in an ester linkage to the OH group on the third carbon atom of the sugar unit …
