BIOLOGY - Genetics - What is DNA

The video tutorial explains DNA's presence in living organisms, its location in eukaryotic and prokaryotic cells, and its role in carrying genetic information. It details DNA's structure as a polymer made of nucleotides, highlighting the four bases (A, T, C, G) and their pairing. The tutorial also covers how DNA determines individual characteristics through genes, which code for specific proteins, and emphasizes DNA's unique nature in individuals except identical twins.
