Sep 13, 2023 · What is the DNA molecule. What does it stand for. Who discovered it. Where is it found. What is it made of. Learn its shape and functions with a diagram.

In order to understand the biological function of DNA, you first need to understand its molecular structure. This requires learning the vocabulary for talking about the building blocks of DNA, …

Jul 23, 2025 · The diagram of DNA structure depicts a double helix structure, with nucleotides forming the sugar-phosphate backbone and nitrogenous bases pairing via hydrogen bonds.

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

Each strand of DNA is a polynucleotide composed of units called nucleotides. A nucleotide has three components: a sugar molecule, a phosphate group, and a nitrogenous base.

DNA is a complex molecule which carries the genetic code. The diagram below shows a tiny bit of a DNA double helix. Figure 12.1.1: The double helical structure of DNA. The backbone of DNA …

Learn about the structure of a DNA molecule with a labeled diagram, including the base pairs, sugar-phosphate backbone, and double helix shape.
