TRANSCRIPTION - 1st part of PROTEIN BIOSYNTHESIS

In this video, I explain the transcription process, the molecular difference between RNA and DNA molecules, why RNA molecules contain the base uracil instead of thymine, and where transcription takes place in cells. For simplicity, I will not explain RNA processing, the process of splicing, and the

What makes RNA viruses so dangerous?

The coronavirus is an RNA virus. An RNA is chemically more susceptible than a DNA. Errors occur more frequently during copying, and the virus mutates. Our immune system reacts slowly to it, vaccine development is more difficult. Author: 3sat/nano/Docstation/Johan von Mirbach/Anna Grün/Riccardo Gies

The origin of life

For life to develop, it needs amino acids, sugars, bases and fats. In addition, RNA, an acid and a kind of chemical Morse code - this is how chains with building blocks are created. But it is only a protective lipid shell that turns the chains into a cell. Author: ZDF/Terrax/R. Schlosshan/F. Hädeck

Personal DNA Testing

In this video from NOVA scienceNOW, take a behind-the-scenes look at the process of personal DNA testing, and hear more about the innovative Personal Genome Project. CREDITS: https://www.pbslearningmedia.org/credits/biot09.biotech.concpt.prsnldna/ LICENSE: https://www.pbslearningmedia.org/help/ful

NOVA: What Darwin Never Knew | Switching Genes On and Off

In this video segment adapted from NOVA, evolutionary scientist Sean Carroll investigates why one species of fruit fly has wing spots while another genetically similar one does not. As the video explains, although two organisms may both possess the same gene linked to a particular trait, this trait

How DNA Replicates

This narrated animation from Interactive NOVA: "The Secret of Life" shows the double helix structure of DNA and how the molecule replicates. The segment illustrates how DNA "unzips" to form templates for the new strands and how complementary nucleotides bind together like the rungs of a ladder. This
