What is CRISPR?
A search-and-cut pair that finds one exact sentence among three billion letters of DNA and cuts it so the cell rewrites it. Bacteria have used it for eons; we learned to reprogram it in 2012; and since 2023 there is an approved medicine that uses it in real patients.
How RNA vaccines work
A temporary instruction manual, wrapped in a fatty bubble, that teaches a few of your cells to build a protein so the immune system learns its face. The mRNA never enters your DNA: the confusion with "gene therapy" is the decade's most widespread myth, and this plate takes it apart piece by piece.
What is synthetic biology
If CRISPR corrects sentences, synthetic biology writes new chapters: designing organisms with instructions that do not exist in nature, from bacteria that manufacture medicines to sensors that change color at a pollutant.
Gene therapy: what is already real
The ledger of gene and editing medicines already approved by regulators: for which diseases, since when, and the honest frontier of what is still in trials. No inflated promises.
