Here's the link for the article.

Here's the link for the abstract, "Direct Imaging of DNA Fibers: The Visage of Double Helix."

Really neat image - thanks for posting.

[Sleeping Freeper]

Really cool! Wonder what Watson and Crick would think.

Wow just Wow-—as we continue to improve our ability to view our universe in a macro and micro way we are yet again humbled, fascinated and energized by the masterstroke of God’s hand.

Great post

i never could understand how they can do gene spicing and NOT be able to produce an image of it...

[TChad]

The helix looks much tighter than in most models.

[HiTech RedNeck]

Chemistry picked apart the structure of molecules way, way before microscopy was competent to visualize them. Diagramming something isn’t the same as getting some sort of direct picture.

[HiTech RedNeck]

Scrunched up like a bottle brush. Diagrams stretch the longitudinal axis to make it easier for people to read them.

[PA Engineer]

The helix looks much tighter than in most models.

Looks like a Fourier analysis could identify some interesting characteristics of DNA.

[Chode]

but how do they know if they get them in the right place/sequence, is it just in the general area or is it hit and miss or do the chemical bonds determine if it will splice properly or not

Wow, judging from what I read there this girl is going to have a big, Roman nose...

[HiTech RedNeck]

I think it works like a regular expression substitution in vi where you know what your desired context is

You might not want to do

:1,$s/foobar/raboof/

but rather something like

:1,$s/my context foobar more context/my context raboof more context/

There has to be a larger stretch in which the edit in question occurs, all chemically mediated of course.

thx...
