T Cell Types and Their Functions

For more Science Videos: https://lt.org/ * T cells are an important component of the body’s immune system. As ERIKA PEARCE explains, there are several types of T cells which form consecutively during the immune response and serve different purposes. Effector T cells combat pathogens from infections

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

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

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
