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
In this video, I explain: the molecular process of translation, the function and structure of the transfer/t-RNA, the translation of the messenger/m-RNA code into an amino acid sequence, the use of the code sun to translate the m-RNA code Original: "Chemistry and biology - get it!" O
LASC offers myriad programs that teach American English and American culture through a research-based curriculum. In our six-level English as a Second Language (ESL) program, students will build the skills and self-assurance to use English in everyday circumstances.
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
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

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
This video excerpt from NOVA uncovers the genetic mystery that nearly killed Alexis, now 14, and introduces the debate surrounding genetic testing at birth. After diagnosing Alexis and her twin brother Noah with cerebral palsy at a young age, doctors later discovered that the twins shared a rare gen
