I have to wonder about how well the OP understands English when she confuses "Switzerland" with "Sweden" ... this is a Swedish study, not Swiss ... [sigh] ... she must be an uppity American or something ...
Also, nowhere in the article does the authors say that mRNA is altering DNA ... the article says mRNA is being reverse transcribed ... I guess we'd have to know that mRNA is transcribed off of DNA ... and that the reverse can happen (
c.f. "Complimentary DNA" in Wikipedia) ... note the researchers added the enzyme, as this enzyme wouldn't be normally available in the liver ...
Fearmongering ... "reverse transcription" and enzyme LIKE-1 are
all trigger words for AIDS ... people will say anything for a buck or two ...
I did delete my comment about Bubbette getting pregnant and dropping out of Middle School ... might be a bit unfair, 3/4's folks here couldn't find the difference between RNA and DNA even after a few days on Google ... Lord knows the confusion if I should bring up tRNA here ...
