The video tutorial covers the basics of DNA, including its structure, function, and significance in genetics. It explains the composition of DNA as a nucleic acid, detailing the roles of nucleotides, sugars, phosphates, and nitrogenous bases. The tutorial also discusses base pairing rules, emphasizing the pairing of adenine with thymine and guanine with cytosine, and how these pairs can be calculated. Finally, it delves into DNA replication, describing the semi-conservative process and the role of enzymes like DNA polymerase in ensuring accurate replication and proofreading.
