DNA transcription and mRNA processing
Transcription involves rewriting genetic information from DNA to mRNA, with RNA polymerase playing a crucial role. In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre-mRNA. This pre-mRNA undergoes processing, including the addition of a 5' cap, a poly-A tail, and splicing out introns, resulting in mature mRNA ...

mRNA vaccine How It Works
Scientists have developed a new type of mRNA cancer vaccine that wakes up the immune system to fight tumors that usually ignore treatment. Instead of focusing on one specific cancer marker, this vaccine tricks the body into thinking it’s under viral attack. This puts the immune system on high alert, helping it spot and destroy hidden tumor cells more effectively. The vaccine works by boosting type-I interferons, natural proteins that kickstart the immune defense when the body senses viruses. Usi

Pharma Giant Pfizer didn’t understand how covid mRNA injections cause the Myocarditis effecting 1/2600 boys. Pfizer called it “rare”, and instead of answering, provided a marketing slogan. As Gerard Rennick exposed their lack of understanding on “the science”, they continually evaded answering, essentially forced to admit they didn’t understand the mechanism by which the vaccine causes myocarditis/ pericarditis. This links with Pfizer admitting: "We don't have a complete understanding of the nat
