Backward thinking, indeed. Modern science has already determined that RNA comes from DNA.
I accidentally unblocked your post and thus saw it but I decided will respond to just this post:
I assume what your are talking about is mRNA being coded from DNA from the cell nucleus of a modern day cell. But that is totally irrelevant to how RNA evolved or came into existence in the first cell that had RNA. You are moronically confusing the two totally different things i.e. confusing the
evolutionary origins with the modern day
metabolic origins. Obviously "evolutionary" doesn't equate with "metabolic".
Actually, your attempt to confuse the two wouldn't work anyway because sometimes the metabolism works the other way around at least when viruses infect i.e. RNA codes for DNA instead of the other way around. this is well known in biology as "reverse transcription" and, just like enzymes translates DNA into RNA, there are enzymes that translate RNA into DNA:
http://en.wikipedia.org/wiki/Reverse_transcriptase
"'...
Reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. RT is needed for the replication of retroviruses
.."
In addition, as if your post wasn't idiotic enough, your statement that "RNA
comes from DNA" is strictly false anyway because it doesn't "come" from DNA but rather it is "coded by" DNA. This is because DNA doesn't "make" RNA but rather an enzyme makes it from scratch by connecting nucleotides that do NOT originate from the DNA itself and uses DNA merely as a template to determine the sequence of RNA bases so that they merely
correspond to the DNA base pairs. Without that enzyme, cells with DNA would not create RNA (and the cell would die ) because, strictly (and correctly ) speaking, DNA itself doesn't actually "make" anything! (although I have seen some of the poorer quality science text books erroneously use the word "make" here, the better ones don't )
If you refute these well known biological fact, just see:
http://en.wikipedia.org/wiki/RNA_polymerase
"...RNA polymerase (RNAP or RNApol), also known as DNA-dependent RNA polymerase, is an
enzyme that produces primary transcript
RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as
templates, a process called transcription...."
-thus it says an enzyme makes the RNA, NOT the DNA itself which is merely used as a template.
As usual, there is just so much wrong and idiotic with your post.
