Biotechnology: Crash Course History of Science #40 

Haha :D - Nick J.

To be fair, if you type Schrödinger into google the first auto-complete is cat. It is clearly what he is famous for :)

Patrick Reding yeah, her own X-rays killed her. Sad.

@Patrick Reding Get. Out.

this channel is useful and i try to make my channel like this

+

Yes, Nice pic btw

streamouss prod Thanks man

really i found it very interesting and i use its information in my channel

CRINGE

I used to work with C. elegans! Hello from one nematode person to another.

@@chillsahoy2640 I work on that one too! Yay nematode friends!

Eyyy, random DCA fan represent!

Mr Shambleface ikr

He managed the ö very well tho, German isn't easy (Swiss German even less).

@@fionafiona1146 The english language has the "ö" sound. Maybe not on its own, but still. I would be more impressed if the "r" wouldn't be the half gargled, half swallowed "r" ;) .

The first half of the name was quite good, while the second had some problems.

Hope your channel goes well

I'm Up Next thank you!!

Biotechnology is a technology that involves the use of living organisms. Biotechnology is mainly used in agriculture, food science, and medicine. In biotechnology, living organisms are used to make useful chemicals and products or to perform an industrial task. So, the used of biotechnology is through DNA sequencing, genomic information is used to create maps of the DNA of different organisms using the biotechnology. Biotechnology, or the use of biological agents for technological progression, has applications in medicine, agriculture, and in industry, which include processes such as fermentation and the production of biofuels. Therefore, this is nowadays are still being used specifically by determining the human genom and phenotype.

Studying life is not complete without studying the biotechnology. And we know that DNA is relates to genes which is related to life. Studying DNA is more like hard to understand on how it connects to each other and how does the genes are being inherited to another generation, how much more when they had discovered DNA. And by this episode it briefly explains how they had studied and discovered the DNA. Biotechnology has a big impact in the history of science because it is related in studying life and many more.

I do not have actually interest about this things like genes, biotechnology and etc. But since it discusses what and how life is I should make some time to understand this thing. Everything is interconnected, by watching this video i learn many things about life, like how this DNAs, genes were the primary twin of life. It drive us in understanding the life. How this thing interconnected to define Life, this biotechnology help us to understand even more the LIFE.

Biotechnology is nearly as old as humanity itself. The food you eat and the pets you love? You can thank our distant ancestors for kickstarting the agricultural revolution, using artificial selection for crops, livestock, and other domesticated animals. When Edward Jenner invented vaccines and when Alexander Fleming discovered antibiotics, they were harnessing the power of biotechnology. And, of course, modern civilization would hardly be imaginable without the fermentation processes that gave us beer, wine, and cheese! Modern biotechnology provides breakthrough products and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, use less and cleaner energy, and have safer, cleaner and more efficient industrial manufacturing processes. Recent advances in biotechnology are helping us prepare for and meet society’s most pressing challenges. Currently, there are more than 250 biotechnology health care products and vaccines available to patients, many for previously untreatable diseases. More than 13.3 million farmers around the world use agricultural biotechnology to increase yields, prevent damage from insects and pests and reduce farming's impact on the environment. And more than 50 biorefineries are being built across North America to test and refine technologies to produce biofuels and chemicals from renewable biomass, which can help reduce greenhouse gas emissions.

In my 8th grade, we had a subject called Biotech. And i always look forward to this lecture since i like science so much and that our teacher is really good at explaining things. We always had fun before with learning about DNA. And i admired of couse Watson and Crick for their discovery of DNA, but i was disappointed upon knowing the real story with them copying Franklin's work. This just shows how greedy humans are just for fame and recognition. It's a sad fact in this world. Regardless, biotechnology advanced with the discovery of dna making people think of endless possibilities to do with it. It's exciting really.

What do you do?

The "cure" is replacing white blood cells by radiation therapy and bow marrow transplant (from someone immune to the strand of HIV in the patient)... That too will keep you on live long imuno suppression, with higher side effects and death rates

But it isn't as easy as removing the HIV strand?

Fiona Fiina is describing what is known as the "Berlin Treatment", I believe. As for removing the HIV itself, the Draco treatment was purported to cause cells with double stranded RNA (which i believe HIV is) within them to self destruct, which could also destroy the immune system of the patient if the infection progresses.

@@TentacleseRex Since a second case has been without sudden death for 2 years now, we might need a new name tho, especially if the Berlin patient eventually dies.

@@orionanderson6719 Well, have you heard of that crazy chinese doctor, who genetically modified human zygotes? It was all over the news a few months ago. I'm a chemist, not a biochemist, but here's the gist of it: HIV is a virus and viruses target specific cells as their host. In the case of HIV it's the white blood cells (which are an integral part of your immune system, which is why HIV is so bad). How the virus can detect which cell is a host cell is rather simple: Cells have proteins on the outside of their cell-membranes. In biochem, those proteins are called 'tags'. Each type of cell has a unique tag, you can think of them as little name tags if you'd like. The virus is blind, but has a protein on it's own, which fits to a specific tag of it's target cell - like a lock and a key. Now back to the story of the crazy chinese doctor: As Hank said in the video, the central dogma in biochem is "DNA to RNA to Protein". To put it more simply: Each section on your DNA is like a blueprint for proteins. Now, remember: That tag on your white blood cells is a protein too. The chinese doctor modified the DNA of two human zygotes in a way, that the DNA section that codes for that protein tag is not readable. Therefore there's no tag and thus the person with that DNA is immune to HIV. The doctor implanted those two zygotes into a woman and she bore two kids, who are - as to my knowledge - alive and healthy. Please bear in mind that, while being able to prevent someone from getting HIV sounds great, there might be side effects, that were not anticipated. And don't even get me started on why this was ethically and morally a very serious issue.

Ironic?

İsn't it a single helix? O_o

Baby don't hurt me

I did a big history project about Rosalind Franklin and it was really interesting. It's horrible how she was treated by her colleagues, and if anybody thinks that James Watson is a hero I'd recommend doing some research.

Billy Trespassers good movie

that's not how any of those work

Yeah but you'd think I would have at least hear it before

So, if a discovery is made by a head researchers' team, that discovery should not be credited to the researcher?

@@BalthusHomewood It should be credited to both the Person who made the discovery, and the supervising head researcher - only giving credit to Rosalind Franklin is wrong, but only giving credit to Ryan Gosling would be wrong aswell. Both are very vital to the creation of the Photo, so both should be credited appropriately.

i read a book "siddhart mukherjee the Gene" it goes along the line of what you are saying. Sci show unfortunately has very opiniated facts.

Me too. Could someone please tell Hank how to pronounce the names of foreign scientists?

guys it’s this one definitely

weird flex but ok
