Understanding DNA and Transcription

The video tutorial explains the storage of genetic material in DNA, focusing on the human genome. It covers gene expression, detailing transcription and translation processes. The transcription process is broken down into initiation, elongation, and termination, with RNA polymerase playing a key role. The video also discusses mRNA processing, including capping, tailing, and splicing. Viewers are encouraged to support the channel on Patreon.
