• DNA stands for deoxyribonucleic acid, and it is the carrier of genetic information within a cell. A molecule of DNA consists of two chains that are wrapped around each other. The chains twist to form a double helix in shape.
  • The DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure and orientation of the two strands are important to understanding DNA replication.
  • This session will explain early experiments in Molecular Biology. Outlined are classic experiments by Avery, Griffith, Hershey, and Chase that demonstrated DNA was the hereditary material, background on Chargaff, Watson, Crick, and Franklin and how their discoveries contributed to the discovery of the structure of DNA, and details regarding how the semi-conservative model of DNA replication ...

DNA. Secondary structure is the set of interactions between bases, i.e., which parts of strands are bound to each other. In DNA double helix, the two strands of DNA are held together by hydrogen bonds. The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the ... This session will explain early experiments in Molecular Biology.
