    Subway Coronavirus Precautions, Dinosaur DNA, and Twitter’s Fleets Feature | The Daily Show

    The coronavirus. The disease is now officially in 85 countries, and it has over 95,000 confirmed cases. And it’s the reason even white people have switched to the fist bump. “And explode.” Now, here in New York, because the city is so crowded, the risk of coronavirus is especially dangerous. Because, you see, if corona can make it here, it can make it anywhere. (laughter) And that’s why city officials are taking action. NEWSWOMAN: The MTA stepping up its cleaning efforts to prevent the spread of the coronavirus on public transit. Workers are disinfecting 427 subway stations, wiping down the turnstiles, handrails and ticket vending machines daily. In addition to…

    DNA Replication in prokaryotes animation

    The race is cannibalised the synthesis of the new DNA strands from the DNA template DNA polymerase is require a pre-existing RNA or DNA spray and primer to initiate new DNA synthesis these polymerase is a deoxyribonucleic Taj only to the three prime end of growing spray and taking a closer look at the nucleotide polymerisation reaction the three prime end of the primer contains a free three prime hydroxyl group the three prime hydroxyl reacts with the five prime end of the next three nucleotide to be added three nucleotides continue to be added to the growing DNA strand by the same type of reaction DNA strand grows in…

    DNA Replication Animation – initiation, elongation and termination

    Process of bacterial DNA replication involves a number of proteins coming together in a complex machine DNA replication begins at a single defined DNA sequence of 245 base pairs called only see a protein called DNA increases in concentration as a cell grows and gets very cell division this protein as a complex with ATP can force the onset of initiation by binding to specific nine base pairs repeat or EC the binding distorts the DNA leading to the opening of the adjacent 13 base pairs repeats in the DNA of the opening of the DNA allows protein complexes to enter the replication bubble and bind to the single-stranded DNA…

    DNA Testing: The Disconnect Between Patients and Researchers | WSJ

    – [Narrator] If you’ve taken a 23andMe test to see if you have a pre-disposition towards Alzheimer’s or used Ancestry.com to figure out if heart disease runs in your family, you’re benefiting from genetic research. That’s because those commercial DNA testing services rely on vast data sets of DNA donated by members of the public to universities. Thanks to this donated DNA, we’ve been able to uncover the role genes play in disease. But what about the donors? Do they fully understand what’s being offered and the limitations of those benefits? This is the result of an ongoing power imbalance. Scientific progress has always relied on the altruism of people,…

    Why keep a journal – Think like a scientist (1/10)

    Hazel, we’re asking the learners on the science experiment course to keep a study journal. And I thought I’d ask you – as dean of science – why taking detailed written notes is good scientific practice. Well, the thing is it’s just like the rest of life. It’s really obvious that day what those measurements or observations or whatever, what they were for, what you’ve achieved, what happened. Next day, next week, next month, certainly next year, you have long since forgotten. And that’s really why. Just so that you understand how the thought processes is and everything else worked out. What the things were that were affecting the experiment…

    Biomolecules (Updated)

    Captioning is on! To turn off, click CC button at bottom right! Follow the amoebas on Twitter (@AmoebaSisters) and on Facebook. I want you to think for a moment about your very favorite food. What is it? Pizza? Macaroni and cheese? Chicken Salad? Sushi? Well we all have different food preferences, but food is a source of large molecules that are needed for life called biomolecules. There are 4 major biomolecules that make up all of life, and this will be the focus of this video. Before we get into details about the 4 biomolecules, we need to talk about one very important vocabulary word. The word monomer. A monomer…

    Genetic Engineering Will Change Everything Forever – CRISPR

    magine you were alive back in the 1980’s, and were told that computers would soon take over everything: from shopping, to dating, and the stock market, that billions of people would be connected via a kind of web, that you would own a handheld device, orders of magnitudes more powerful than supercomputers. It would seem absurd, but then, all of it happened. Science fiction became our reality, and we don’t even think about it. We’re at a similar point today with genetic engineering. So, let’s talk about it. Where it came from, what we’re doing right now, and about a recent breakthrough, that will change how we live and what…

    You're Already in the Machine – You are Food for the World Wide Web

    you are already in the machine welcome to the World Wide Web The Matrix is more nonfiction than science fiction we have the man the legend the way of life and before I do anything else I have to hit the pause button we're gonna get an echo echo echo Wayne Steiger is with us he's got a really cool YouTube channel he does podcasts on a regular basis a lot of mine candy and he sent me an email earlier today and he said Rex are you ready for this do you know what IP address stands for well I'm gonna let him share it with you guys but…
