The video tutorial explains the process of transcription, where DNA is transcribed into RNA. It begins with an introduction to RNA and the role of RNA polymerase in separating the DNA helix. The tutorial details how RNA nucleotides match with DNA strands, emphasizing the absence of thymine in RNA. It covers the steps of transcription, including the unzipping of DNA and the synthesis of RNA. The video also explains RNA processing, highlighting the removal of introns and the splicing of exons by the spliceosome. Finally, it transitions to the concept of translation, where mature mRNA is used to synthesize proteins, and concludes with a practice quiz.
