one of three things is at play here:
1 cannot read
2 no reading comprehension
c lack of understanding of science
or any combination of the above...
hover your mouse above the picture in the document and read the text
also the left side of the picture shows RNA as one of the parts of gene therapy
and the right side of the picture shows "lipid nanoparticle" which is used in the mRNA vaccines along with a "viral vector" which is how astra zeneca and johnson and johnson work
the opening sentence of your "proof" says "Human gene therapy seeks to modify or manipulate the expression of a gene or to alter the biological properties of living cells for therapeutic use"
the second paragraph includes this "Gene therapy is a technique that modifies a person’s genes to treat or cure disease. Gene therapies can work by several mechanisms:
...
...
Introducing a new or modified gene into the body to help treat a disease"
i would say "try again", but the for the reasons stated above, i doubt you can
i also doubt that you will admit you were wrong for posting a document claiming to correct something when in actuality, you confirmed it
