The video explains the central dogma of molecular biology, detailing the flow of genetic information from DNA to RNA to protein. It covers DNA replication, transcription, and translation processes, highlighting the roles of DNA polymerase and messenger RNA. Exceptions to the central dogma, such as retroviruses, are discussed. The video also explains mRNA processing in eukaryotes, including the addition of a 5' cap, poly-A tail, and RNA splicing. Key terms like introns, exons, and spliceosome are defined, and the importance of these processes in genetic information flow is emphasized.
