It's a double helix.

So there's a strand that goes like this, goes along one helix and binds it jumps to another helix and comes back.

So Wilkins said he thought it was the helix.

This is DNA in its classic double helix form.

You'll be familiar with the double helix of DNA.

X ray diagram, he thought was comparable with the helix.

You mix them together and they make a rigid double helix.

And you can see a little bit of double helix forming there.

We want to look at individual strands and not think about the double helix.

And when you're done, it makes this design, which, if you squint, is the word helix.

If we unwind the double helix and unzip the two strands, you see these things that look like teeth.

It's double stranded, it's a double helix, has the As, Ts, Cs and Gs that pair to hold the strands together.

He certainly wasn't smiling when I got there, because he was somewhat humiliated by Pauling getting the alpha helix, and the Cambridge people failing because they weren't chemists.

So if you zoom in on this genome, then what you see, of course, is this double helix structure the code of life spelled out with these four biochemical letters, or we call them bases, right A, C, G and T.

When you look at DNA origami, you can see that what it really is, even though you think it's complicated, is a bunch of double helices that are parallel to each other, and they're held together by places where short strands go along one helix and then jump to another one.

LONDON On April 25, 1953, Francis Crick and James Watson published a one page paper that many believed would revolutionize biological research. Building on the work of Rosalind Franklin and Maurice Wilkins, they had discovered DNA s double helix structure, providing the first glimpse into how organisms inherit and store biological information.

And when Watson and Crick in the '50s first decoded this beautiful double helix that we know as the DNA molecule very long, complicated molecule we then started on this journey to understand that inside of that DNA is a language that determines the characteristics, our traits, what we inherit, what diseases we may get.

High on past positive. Moderately high on future.

And these are high school kids teaching high school kids.

If low high, the sequence will be from high to low.

High tech, high touch. Isn't that what some of you said?

Secondary education includes junior high or middle schools and high schools.

So they started flying them at high altitudes at incredibly high speeds.

You can get a Mercedes for a very high price, very high performance.

University enrolment was high, with comparatively high rates of employment at executive levels.

The high literacy rate had resulted in high standards of maternal and childcare.

They had high, or very high, child mortality and family size, six to eight.

That's extremely high.
