Exploring the Fundamentals of DNA and Genetics

This video tutorial explains DNA, its location in cells, its function in carrying genetic information, and its structure. DNA is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. It is a complex molecule that determines the characteristics of living things through genes, which code for proteins. DNA is made up of nucleotides, each containing a phosphate group, a sugar group, and a nitrogen base. The four bases, adenine, thymine, cytosine, and guanine, pair up to form the double helix structure of DNA.
