how the RNA was created

For all those biophiles interested. A plethora of youtube videos to be posted at a later date. Thanks to Wikipedia

Synthesis of RNA is usually catalyzed by an enzyme—RNA polymerase—using DNA as a template, a process known as transcription. Initiation of transcription begins with the binding of the enzyme to a promoter sequence in the DNA (usually found "upstream" of a gene). The DNA double helix is unwound by the helicase activity of the enzyme. The enzyme then progresses along the template strand in the 3’ to 5’ direction, synthesizing a complementary RNA molecule with elongation occurring in the 5’ to 3’ direction. The DNA sequence also dictates where termination of RNA synthesis will occur.

RNAs are often modified by enzymes after transcription. For example, a poly(A) tail and a 5' cap are added to eukaryotic pre-mRNA and introns are removed by the spliceosome.

There are also a number of RNA-dependent RNA polymerases that use RNA as their template for synthesis of a new strand of RNA. For instance, a number of RNA viruses (such as poliovirus) use this type of enzyme to replicate their genetic material.Also, RNA-dependent RNA polymerase is part of the RNA interference pathway in many organisms.

I don't know if I'm nuts about guns. I kind of like them.

Man, whatever you do, don't let Viceroy63 from the evolution thread see this: "...RNA was created".

Anyway, one model suggests that - in terms of the development of life - RNA could initially just about function/replicate without fully-fledged enzyme activity in a way which DNA could not. So, by this model, all it takes is a few nucleotides to line up and see how things go on from there.

What you've described is how RNA is created.

Could be, I don't read the Community Guidelines anymore.

Also, this is pretty clearly its own unique informative topic.

Wait, wut? Don't rat me out. I thought it was a good clean way to entertain everyone*.




*Ok fine. Like 7 of us. But I still thought it was ok.

Face it. You and your two dimes are going to prison.

Take FT with you.




PUHleeeease.

OK, I like FT.

Actually, it is pretty interesting, even if this was largely a parody thread Good to have a refresher.

Anything on how RNA is involved with Triploid activity? I remember hearing something about that way back, but cannot remember the details.
