Strawberry DNA – Food Science | Science Experiments | Steve Spangler Science

In this lab, you extract and isolate DNA from strawberries using simple, household ingredients.

You’ve probably learned or heard about DNA, but have you ever seen it? With the Strawberry DNA experiment, you’ll extract, isolate, and observe the DNA of a strawberry in a matter of minutes. It sounds impossible, but thanks to special characteristics of strawberries, it’s actually very possible… and simple. You don’t have to be a geneticist and you don’t need an electron microscope. It’s easy, fun, and all you need are some household materials.

Your Amazing Molecular Machines – Veritasium

Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old – this is normal, in fact it’s called programmed cell death.

To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells.

And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start – the double helix molecule that we always talk about.

This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C.

Is DNA the future of data storage? – TED- Ed Leo Bear-McGuinness

In the event of a nuclear fallout, every piece of digital and written information could all be lost. Luckily, there is a way that all of human history could be recorded and safely stored beyond the civilization’s end. Continue reading
