So a month or so ago a paramutation phenomenon involving non-mendelian inheritance was discovered in mice. Evidence in that paper suggested that genetic information was passed on through a germ cell pool of RNA in addition to DNA. Interestingly, another Nature paper now shows that the more well-known phenomenon of paramutation in Maize relies on an RNA-dependent RNA polymerase known to be involved in the production of siRNAs. The idea is that this enzyme makes RNA molecules that affect heritable chromatin states that in turn affect transcriptional activity.

and with prove like this, the human still wanted to make all to their will, guess what? nature is more fast and intelligent than us.
hello there, I really like this blog because is a slightly atypical blog, since most of them are about nature works and biological issues, and also I enjoy to read something about it.
