If this does occur, the DNA changing itself, then it has some sort of plan as to what is supposed to be like - to do. bill w</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Feb 10, 2019 at 8:46 PM John Clark <<a href="mailto:johnkclark@gmail.com">johnkclark@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">On Sun, Feb 10, 2019 at 7:52 PM William Flynn Wallace <<a href="mailto:foozler83@gmail.com" target="_blank">foozler83@gmail.com</a>> wrote:<br><br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">> <i> the CRISPR book I read said something about RNA(?) that went up and down the DNA making changes (sorry - can't remember more) - maybe a sort of editing?</i></blockquote><i><br></i><br><font size="4">You're correct, the full name is CRISPR/Cas9. <span style="line-height:1.5">CRISPR part is a short sequence of RNA that is complementary to the place on the DNA that you want to edit.</span><span style="line-height:1.5"> The Cas9 is a protein enzyme that cuts DNA with a slight overlap rendering the ends sticky so its easy to insert a gene there. The RNA positions the Cas9 with great precision so the cut is make just where you want it to.
