  2. Can an RNA vaccine change your DNA permanently?

    skeptics.stackexchange.com/questions/48250

    The mRNA in an mRNA vaccine alone cannot edit DNA. In the CRISPR gene editing method the actual act of cutting the DNA to edit it is performed by Cas9, which is an enzyme, not RNA.

  3. Do humans share 99% of their DNA with rats?

    skeptics.stackexchange.com/questions/13902

    Sharing 99% of genes is not the same as sharing 99% of DNA. While we may have nearly the same number and type of genes (i.e. rat genes have counterparts in the human genome) it does not mean that these genes are completely identical. They are comparing the number and function of the genes only.They are NOT comparing the actual DNA sequences.

    (I have wondered about this question before when this video was doing the viral rounds.My cynical supposition was that the producers were manipulating the subjects, knowing that, for example, the man who thought his ancestors were Icelandic for many generations could never get a "100% Icelandic" result from the tests that were run, no matter what his genes.

    At a minimum, spontaneous formation of: two rRNAs with a total size of at least 1000 nucleotides. ~10 primitive adaptors of ~30 nucleotides each, in total, ~300 nucleotides. at least one RNA encoding a replicase, ~500 nucleotides (low bound)is required. In the above notation, n = 1800, resulting in E <10 -1018.

    UVC is effective against SARS-CoV-1, but efficacy of the applied dose (a function of irradiance and time) appears to be highly dependent on many factors, such as inoculum size, culture medium, and shape and type of material likely explaining the highly inconsistent findings in the published literature. 3.1. Ultraviolet germicidal irradiation (UVGI)

    skeptics.stackexchange.com/questions/57256/do-metal-objects-attract-lightning

    Myth: Structures with metal, or metal on the body (jewelry, cell phones,Mp3 players, watches, etc), attract lightning.
