Biomarker Discovery and Endpoint Refinement 1 - Image Index | 20 Ways AI is Advancing Clinical Trial Management Visualizing the Double Helix: A Closer Look at DNA Structure: A double helix DNA strand, which is the fundamental structure of DNA. The DNA molecule is composed of two complementary strands that are twisted together in a spiral fashion. Each strand is made up of nucleotides, which are the building blocks of DNA. Nucleotides consist of three components: a sugar molecule called deoxyribose, a phosphate group, and one of four nitrogenous bases - adenine (A), guanine (G), cytosine (C), and thymine (T). The sequence of these nitrogenous bases determines the genetic information encoded in the DNA. In this image, the DNA strand is depicted as a double helix structure, with the sugar-phosphate backbone on the outside and the nitrogenous bases projecting inward from the backbone and pairing up with each other in a complementary manner. This pairing is crucial for the replication and transcription of genetic information. The blue color represents the sugar-phosphate backbone, while the orange color represents the nitrogenous bases. The image provides a clear visual representation of the double helix structure of DNA, highlighting its importance in genetics and molecular biology.
