I put my DNA under the microscope and you can too 🔬 Easy DNA extraction 

You have to take genetic engineering as a career

Me too, now im grade 10 we are learning about gender 127

Exactly you are right I am in class 11 now

​@Scott Pickering how is this "basic" science? because he made it seem easy using common materials?

​@Scott Pickering ​ @Scott Pickering in what reality? hopefully the one where actual scientific thinking applies what "basic science" do you figure out what is or is not dna in a pool of stuff? how do you know what breaks down proteins and cells to get at dna? how do you know how to separate dna from other things? can you explain the "basic" science to get at all of the information being presented for each step? So, since its "common materials" it's "basic"? regardless of how many non-"basic" sciences use common materials in a lot of their processes. "its looking at stuff through a microscope".... this is like saying "its looking at stuff using a calculator/computer" for rocket science.... If you just "looked at stuff through a microscope", would you know what you are looking at at all? Keep in mind how he can't verify that these things are indeed dna or not, or if the clumping is from protein or not; he's making educated guesses based on "basic" science? Do you think "astrophysics or rocket science" can't have small inaccurate experiments like this that make things seem "basic" because it's not a "basic science"? How exactly do you define "basic" science, because I don't see a consistent approach being used here.

It could be condensed chromatin fibers, which is roughly 700 nm wide. That could be seen with a light microscope I think.

why do we see alpha-amylase proteins after eating starch?

@@tannukashyap8311 Looking back on this you wouldn't be able to actually see the proteins like that, too small. I think I was assuming there is an increase in alpha amylase enzyme production in your mouth during starch consumption to help increase digestion, but I don't actually know if that's true

@@SystemUpdate310 I think it's possible to see 700nm in a light, and yes it is condensed chromatin fibers, heterochromatin is 700

@@tannukashyap8311 they are enzymes used in the digestion of starch So if you eat a lot of starchy food, then your cells (Intestinal for this one in particular) would respond by synthesizing more alpha amylase enzymes To help in the digestion of it

🇱🇰❤

Yes! I'm!

Totally magnificent dear

Exactly :)) people should show their more interest in science ...

Najma Samantha...Microscopy, and amateur astronomy are the best hobbies anyone can get into!..It sure beats coin, and stamp collecting which I find to be dull, and boring!

@@damontsekos365 hobbies are subjective. I find stamp and coin collecting boring as well but you can’t go around telling people what they should be more interested in

People are suprised that I’m 11 and I like science and not stupid video games

Hai Apoorva were is our college in India

Academia has an agenda ,,,keep them dumb ,,,,not too dumb.Evil to the lying core.

Absolutely!! 100%

tell him then

yeah i agree

Wow excellently cool experiment

U amplify electricity not magnify it. but if you're really really really want to magnify it then buy an oscilloscope.

❤Thanks

You need a oscilloscope

Good question

It is DNA

@@МиленаКамчева Лаборантка? :)

point of classes at university is to give you the background to allow you to get to these types of things on your own, designing and figuring things out. just watching and learning specific things is mostly only beneficial for a particular job or task. it can be more motivating because its more interesting, but it should motivate you to learn the class stuff.

Then you must not be paying attention in your university classes...

Not too late my friend, sit down, make plans and go for it, live while you are alive.

Jesus, SEMS are very specialised and expensive! Based on many factors and the functionality I would so prefer a expensive compound microscope. But I guess its down to opinion, I hope you will be satisfied 😌 Aplogies to my terrible communication, I am much more used to typing on a computer then typing over a compact electronic device like a phone.

It's an Olympus BX53 with Planfluorite objectives (4x 10x 20x 40x 100x oil) and Differential Interference Contrast (DIC), which is expensive but produces very nice images. You need a separate prism for each objective and they need to be fit in into a condenser with a rotating turret. I obtained several offers, all similar in the price range, some even more expensive.

@@Microbehunter OoO an Olympus! I hope to be able to donate too!

me too mate.

I'm trying to do a project on this...your support would be very helpful!

I did not measure anything, i estimated. Spoon of salt in 100ml water, drop of liquid soap, 96% ethanol.

@@Microbehunter ok thanks so much!

yes, but there is no need to differentiate, he does not have the resouces to do so as well. The point of the video was to extract DNA and see if it can be seen in the microscope. Also, he used saliva as the sample, you could guess how much DNA is from bacteria.

I have used 96% (about) ethyl alcohol. It works better when the alcohol is ice cold, but I did not cool it and it also worked. The DNA participation with alcohol is standard procedure in molecular biology. The alcohol reduces the polarity of the water to the extent that DNA can not be dissolved anymore. Normally one would collect the DNA by centrifugation after the addition of alcohol.

It's an Olympus BX53, LED, Plan Fluorite 4x, 10x, 20x, 40x, 100xoil DIC Prisms, one for each objective, Wollastone Prism etc. things that are required for DIC. It produces extremely pretty images, though.

@@Microbehunter Well Oliver, I can't think of a better person to have such a microscope. I'm sure you will do wonderful things with it. Good luck!

I am using an Olympus CH-40 and an Olympus CHA with phase contrast. Other microscopes should also work.

So you would say it is DNA that we are seeing?

I study b SC biotechnology 1st year. In my practical we do Isolation of DNA from both plant and animal tissue. it's gave a best results.

The microscope must be good and I also used phase contrast. If the microscope has a proper condenser, then maybe yes.

Can't spit ants into tt?

Biotech is taught in high school for 2 months or a year at max. But to understand it people learn for years.
