MICROBIOLOGY QUESTIONS REGARDING VIRUS TREAMENTS.
So,for many years now I have been contemplating virus treatments for cancer cells. now I am by no means an expert on Microbiology. However enjoy discussing theories. I am sure you have heard a million theories before from people more intelligent than me,but let me just get this idea out.

step 1. Replace Rotavirus RNA with healthy human DNA

step 2. Infect affected area with virus

step 3. Rotavirus attaches to a cell (cancerous or not it doesn't matter ) cell is infect and new DNA is inserted by rotavirus

assumption 4. RNA of human cell copies virus injected DNA recoding original?

assumption 5. virus replicates and moves on to next cell

assumption 6. virus repeats steps 1-5 until complete infection

here are my questions and issues.

I have not thought about this in many years.

1.originally rotavirus is double stranded RNA. so can it be replaced with DNA and should it? if IT is replaced by a single strand of DNA (or RNA NOT SURE WHICH IT SHOULD BE) Will human cell RNA copy healthy DNA strand?

I base this on rotavirus because it does not destroy cells


if human is infected by virus is (he/she) then immune to mutation of cells since virus continues to up keep cell dna



problems if virus caries human dna then does it cause mutation in other humans? because they dont share the same dna?
