Once those bits of DNA have been inserted into the bacterial chromosome, the cell then makes a little copy of a molecule called RNA, which is orange in this picture, that is an exact replicate of the viral DNA.
What are the building blocks of a water molecule?
Now, you can think of that as the backbone that holds the rest of the molecule together.
Now, I know that seems crazy, but your body doesn't care what a molecule looks like on paper.
All that matters is the 3-D shape where the molecule fits, where it doesn't, and what pathways it interferes with.
So, pushing past them with your gigantic body is easy, but if you were really small, say you were about the size of a water molecule, all of a sudden, it's like you're swimming in a pool of people.
Rather than simply swishing by all the teeny, tiny molecules, now every single water molecule is like another person you have to push past to get anywhere.
Every atom and molecule has a set number of possible energy levels for its electrons.
To shift its electrons from the ground state to a higher level, a molecule needs to gain a certain amount of energy.
Sunlight offers all the photons of the rainbow, so a gas molecule can choose the photons that carry the exact amount of energy needed to shift the molecule to its next energy level.
When this match is made, the photon disappers as the molecule gains its energy, and we get a small gap in our rainbow.
If a photon carries too much or too little energy, the molecule has no choice but to let it fly past.
Shortly after a carbon dioxide molecule absorbs an infrared photon, it will fall back to its previous energy level, and spit a photon back out in a random direction.
And for the last 10, 15 years, this was so special to me, because this molecule has turned out to be one of the most revolutionary tools in biomedical science, and it's allowing us to better see inside ourselves.
Inside each of these cells, chemical reactions are constantly occurring, powered by the glucose and oxygen that our bodies convert into the energy-carrying molecule known as ATP.
First, scientists dissolve boiled egg whites in water with a chemical called urea, a small molecule that acts as a lubricant, coating the proteins' long strands and making it easier for them to glide past each other.
It's also how renowned chemist August Kekule discovered the structure of the benzene molecule, and it's the reason that sometimes the best solution for a problem is to sleep on it.
These biomolecules have a property called chirality, which means that a molecule and its mirror image aren't identical.
When it receives this message, the hypothalamus produces another molecule called prostaglandin E2, which gears it up for war.
These dedicated nerves produce a molecule called natriuretic polypetide B, which triggers a signal that's carried up the spinal cord to the brain, where it creates the feeling of an itch.
Each siRNA molecule can turn off a specific gene inside the cell.
Basically, there's a protein that acts like a scissors and cuts the DNA, and there's an RNA molecule that directs the scissors to any point on the genome you want.
Well, the signal is just a molecule.
If we want to use a really sensitive, fancy instrument called a mass spectrometer, then we make a molecule with a unique mass.
I could pour much more of this in there, but I think you've got the idea that this is a very, very interesting molecule, and if can use it in the right way, we might be able to really zoom in on the brain in a way that you can't do with past technologies.
DNA is the fundamental molecule the carries genetic instructions that help build the living world.
Your genetic information is strung into a long and twisted molecule, the DNA double helix, that has over three billion letters, beginning to end.
Now, what you can see here is essentially a sugar molecule that was added a small little tag that is signaling to us outside of the body, "Hey, I'm here."
Each individual water molecule doesn’t have a tide, but the whole ocean does.
She's elegant and smart, building with what's available, molecule by molecule, making structures with a complexity and a diversity that we can't even approach.
