Exploring DNA Structure and Replication

The video tutorial covers the structure and replication of DNA, explaining its role as genetic material. It introduces nucleic acids, focusing on DNA and RNA, and describes their building blocks, nucleotides. The tutorial details the nitrogen bases and their pairing rules, emphasizing the double helix structure of DNA. It contrasts DNA with RNA, highlighting structural differences. The process of DNA replication is explained, including the role of enzymes and the concept of semi-conservative replication.
