Simplemente, me encantó
von Avril L. am 01. März 2024 für Background of Enzymatic Reactions – Enzyme Catalysis

Me encantó como lo ha explicado, paso a paso, de manera detallada y concisa. He aprendido mucho gracias a este video, ¡gracias!

 
Excellent lecture.
von Mariana . am 23. Januar 2024 für The Levels of Eukaryotic Gene Expression

Dr. Georgina turns difficult topics in genetics into clear and simple concepts that are easy to digest! For the first time I feel like am starting to understand the Central Dogma and related subjects better thanks to her. She's also greatly commited to student success by answering to students questions and concerns about the subject.

 
Good course!
von Nicolas W. am 17. Januar 2024 für Carbohydrate Metabolism

To the point. Good organized pathway explanations. Pedagogical presentation skills.

 
Great, straight to the point lecture.
von Mariana . am 13. Dezember 2023 für Overview of Transcription and Translation

I like how she breaks down the information in small and easy to understand pieces. There's no need to overcomplicate things like other science teachers love to do.
