it'd be cool to have a video like this but which would explain (briefly) the "why" of each step.

You think they know that? They can't even image DNA clearly enough to see anything of note. Science has been hijacked since the mid 1850s. Good luck finding a paper that leaves no doubt in your mind that the mystical double helix exists, nevermind a paper proving DNA/RNA protein synthesis is occurring as the many animations portray.

This video is so much in first person view! I wonder, where in the world are you placing the camera? In front of the technician? It is a great angle.

What If you spill the Dna solution on the Table, how to remove It, with a towel? What If your gloves have a hole and you get DNA on your skin, what Happens? Are there Information Materials for what do to when Things Like this Happens ?

What is function of vortex?
@AA-wd2or3 жыл бұрын
A vortex mixer, or vortexer, is a simple device used commonly in laboratories to mix small vials of liquid. If sample sit long time can be to stiff , so you mix it to relax it.,It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup (or touched to its edge) the motion is transmitted to the liquid inside and a vortex is created. Most vortex mixers are designed with 2 or 4-plate formats, have variable speed settings ranging from 100 to 3,200 rpm, and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece.

Why should anybody try air-drying those DNA-pellets, if the workplace is not sterile? lmao btw: It wont take 20min to evaporate a tiny drop of 70% EtOH

@eternal footman DNA isn’t always in the supernatant, it can be in the pellet or the supernatant (depends on the solvent you’re adding before the centrifugation)
@ixayla6 жыл бұрын
Why did you discard the supernatant this time, not the pellet?
@lilna74446 жыл бұрын
Because pur ethanol precipitates DNA, thus the pellet contains DNA, and we want to keep it ;)
@gilian25873 жыл бұрын
The centrifuge separates heavier material from lighter material. The first time through the centrifuge, the dissolved cell walls and larger cellular structures were clumped to the bottom. The second time through; the only two components left were the ethanol and the DNA, and DNA is heavier, so it clumped to the bottom the second time. (When I say heavier in this context, I mean 'more dense')
