RNA interference (RNAi): by Nature VideoMay 17, 2012
RNA interference (RNAi) is an important process, used by many different organisms to regulate the activity of genes. This animation explains how RNAi works and introduces the two main players: small interfering RNAs (siRNAs) and microRNAs (miRNAs). We take you on an audio-visual journey, diving into a cell to show how genes are transcribed to make messenger RNA (mRNA) and how RNAi can silence specific mRNAs to stop them from making proteins. The animation is based on the latest research, to give you an up-to-date view. If you'd like to know more about the structures and processes you see in this video, check out the accompanying slideshow: www.nature.com

DNA and RNA - Part 2May 16, 2012
027 - DNA and RNA - Part 2 Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA and is finally translated into proteins. He also introduces genetic engineering and explains how transformation is used to create insulin.
RnA Drops Review - Weird Stuff Is Happening...May 14, 2012
www.exploringinfinity.com Click The Link If YOU Want Weird Things To Happen RnA Drops Review - Weird Stuff Is Happening... www.youtube.com Get a FREE TRIAL of RnA Drops: www.RnAfreemini.com You have to pay shipping though! After trying RnA Drops I HAVE TO do a review... This stuff is weird, but I like it. I got a trial bottle for free from a friend who wanted me to give them a try and see what I thought, so I decided to give them a go. When I first started watching youtube and looking for more information about RnA Drops I started to think that it was a total hoax. The videos from "iON" and his friends trying to explain the drops made me think they were just lunatics involved in some RnA Drops scam, but I got the drops for free and said I would try them, so I decided to try them anyway. I wouldn't have ever bought a bottle of the drops if I hadn't been given one for free to try first, because to me it just didn't seem legit after watching the youtube videos and reading around the RNA Drops websites... But since it was free I tried them, and I'm glad I did. The weird part is that after being on the drops for about 2 weeks I started to not really need much sleep. Ive been staying awake for about 30 hours before getting tired. Most of the time this would probably be considered a bad thing, except that during the time awake I am more productive than I normally am without RnA drops and WITH sleep! There's nothing else I can think of that would be causing me to not need as much ...
RNA SplicingMay 10, 2012
A 3D animation shows the crucial RNA editing step called splicing Originally created for Learn About Spinal Muscular Atrophy ( www.learnaboutsma.org ) TRANSCRIPT: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. This editing process is called splicing, which involves removing the introns, leaving only the yellow, protein-coding regions, called exons. RNA splicing begins with assembly of helper proteins at the intron/exon borders. These splicing factors act as beacons to guide small nuclear ribo proteins to form a splicing machine, called the spliceosome. The animation is showing this happening in real time. The spliceosome then brings the exons on either side of the intron very close together, ready to be cut. One end of the intron is cut and folded back on itself to join and form a loop. The spliceosome then cuts the RNA to release the loop and join the two exons together. The edited RNA and intron are released and the spliceosome disassembles. This process is repeated for every intron in the RNA. Numerous spliceosomes, shown here in purple, assemble along the RNA. Each spliceosome removes one intron, releasing the loop before disassembling. In this example, three introns are removed from the RNA to leave the complete instructions for a protein.
RNA (Ribonucleic Acid)May 03, 2012
This is a tutorial/lecture on RNA - Ribonucleic Acid. We cover some topics important for classes such as Molecular and Cellular Biology or Biochemistry. List of topics: - Description of general structure; - Self-complementary hairpins or stem loops; - Types of RNA: mRNA, rRNA, tRNA, pre-mRNA, pre-rRNA, ncRNAs. If you have any questions, don't be shy!! We hope we are able to clarify this topic. Enjoy!
