Should some knowledge remain unknown?

Great. Now see what codons they form, (among themselves or *with* the existing four bases), what they code *for*, and the relative affinitiees of different substrates one to another.
Oh, and how do they react to methylation?

Why screw with what exists? Why do you need synthetic base pairs when natural ones work as they were were created to?

Interesting, with big implications in the data storage and retrieval biz. Not so much in life functions, though, at least not yet:
The researchers could potentially use their synthetic DNA to create novel proteins as well as RNA.
The problem is: do they code for anything? That is, do they make proteins? Can we incorporate them into tRNA attached to anything that binds?
It's pretty exciting stuff, actually, but building a meaningful protein isn't just getting a sequence right, it's figuring out how the thing folds into a useful morphology. We're taking baby steps here, but they're forward.

It is a predicament. Until you know
something, it cannot be knowledge.
It’s unknown. But as soon as you know it,
voila, knowledge! And there’s no going back.
But if you don’t know it yet, it isn’t
knowledge, and nobody knows.
Or something.

No. Because it will eventually be learned. Also the potential for good is too great to ignore. Curing cancer. Creating new forms of life . Who knows maybe that’s how we arrived on earth. ETs may have sent our building blocks to earth and let the magic happen.

Only for a while.
But remember what the great Bob Seger sang; “I wish I didn’t know now what I didn’t know then.”

So, it seems that we’re 4-bit life forms; and, we may be rendered obsolete by 8-bit life forms. Or not.
To: Tolerance Sucks Rocks
And yet there’s still no “gay gene”...
Bummer.

I don’t know much about DNA but I did score well on the GCAT test.
To: Billthedrill
I have read that proteins find the correct folding pattern way faster than pure chance would allow, indicating the proper folding is itself somehow encoded in the DNA. Further a misfolded protein is a prion and is what causes conditions like CJD, Kuru, and Fatal Insomnia.
