You zoom in, there are just four DNA strands and they have little single stranded bits on them that can bind to other tiles, if they match.

When we synthesize it, it comes single stranded, so we can take the blue strand in one tube and make an orange strand in the other tube, and they're floppy when they're single stranded.

All this field of view is a single strand of DNA.

And if you want to take a single crystal of DNA, it looks like that.

Double strand again, but inside them, they're infected with a virus that has a nice, long, single stranded genome that we can fold like a piece of paper.

The chemical inhibitors used in this treatment target the enzyme polymerase (PARP1), which is normally involved in the repair of DNA single strand breaks a common form of spontaneous DNA lesions. Chemical inhibition of the PARP1 protein results in reduced occurrence of these single strand break repairs.

But to do it, you need a long, single strand of DNA, which is technically very difficult to get.

Two DNA sequences generated at random must be 25 identical, by virtue of the fact that DNA is a sequence of only four bases. Therefore, all multicellular life, having presumably developed from a single common ancestral form, must be over 25 identical in their DNA sequences.

So we built a three stranded model.

So, all you guys have heard about DNA, all the stuff that DNA does, but some of the stuff we're discovering is kind of nifty because this turns out to be the single most abundant species on the planet.

The 0.1 of the genome that was different (approximately 3,000,000 bases of DNA) was comprised of single nucleotide polymorphisms (SNPs are alterations of the individual bases of DNA) scattered throughout the genome. It was thought that some of these DNA alterations may in part explain some of the physical differences that exist between two different, but otherwise normal individuals.

It was the first DNA phage, DNA virus, DNA genome that was actually sequenced.

Now it wasn't DNA she didn't find DNA.

Tonight, there will be 10 flights to help stranded tourists returning home.

The quake destroyed thousands of buildings and left thousands of tourists temporarily stranded.

And so there was the paper, and he proposed a three stranded structure.

One set of DNA goes to one side, the other side gets the other set of DNA identical copies of DNA.

So, this is normal DNA, what you think of as normal DNA.

And you can make a map of the Americas and spell DNA with DNA.

It's humanity's DNA.

DNA at 60

So we have discovered that dinosaur DNA, and all DNA, just breaks down too fast.

The next thing is, that virus DNA made stuff that chopped up the bacteria DNA.

Already, variations in the composition of about 500,000 DNA building blocks (SNPs or Single Nucleotide Polymorphisms), spread over the total length of the DNA and shown to correlate with particular physical and behavioral characteristics or susceptibility to diseases, are being analyzed routinely. Major errors in DNA composition that are responsible for about 3,000 of the 7,000 known genetic diseases can be visualized, and efforts are underway to identify the causes of the remaining 4,000.

We have our nucleic DNA that everybody thinks of as our DNA, but we also have DNA in our mitochondria, which are the energy packets of the cell.

This is crystallized DNA.

So that's DNA origami. That's one way. There are many ways of casting molecular spells using DNA.

You can look in this computer fabricated artifact, and he's got a double stranded genome that's no good.

I extracted DNA from them.

But it's not dinosaur DNA.

And DNA also copies itself.

They're encoded in the DNA.

Paul Rothemund details DNA folding

It feels the DNA origami.

And it has no DNA.

Synthetic DNA, the ability to synthesize DNA, has changed at sort of the same pace that DNA sequencing has over the last decade or two, and is getting very rapid and very cheap.

To ensure safety, airline flight crews assisting stranded tourists to return home have made plans for the impact of

If you were stranded on a desert island, what books would you want to have with you to read?

But I want to talk about a different aspect of DNA science, and that is the physical nature of DNA.

We're not DNA zealots, but DNA is the cheapest, easiest to understand and easy to program material to do this.

So again, we begin with DNA.

Now, a quick primer on DNA.

DNA is a very elegant molecule.
