Researchers look into components of RNA silencing machinery
...rson's DNA is believed to be junk DNA. In order to prevent
these relics of evolution from rearranging chromosomes and causing disease, natural mechanisms exist to silence them, according to contemporary theories of chromosome biology. The RNA silencing machinery silences gene expression, by destroying RNA...
