Gel structure

Hey, Does anybody has the software or web site about RNA second structure? I download the Vienna Package but it dose not work. What else can be used for folding RNA sequences? Thk u.

... very much, Canalon. However, I do question your notion that DNA should be counted as two molecules. The joining by hydrogen bonds qualifies the structure as a single molecule. By that reasoning you would always be looking at the vast number of single complex molecules that can be recognized ...

Does each chromosome in a human cell contain one complete DNA molecule, so that there are 46 separate DNA molecules, one for each chromosome? Or does a single DNA molecule continue as an extended filament, running in and out of one chromosome, then proceeding to the next--eventually threading its wa...

You must have looked long and hard. The structure is visible here: http://en.wikipedia.org/wiki/Fatty_acids And the strength of the acid is determined by the electronegativity of the chain behind the "acid H". You can see her a little ...
