In this lesson, we explore the essential gene mutations on Drosophila flies during development and their embryology effects: gap genes, pair rule genes, and segment polarity genes.
Where does DNA transcription start and stop? In this lesson, we explain how DNA transcription works, the start and stop of transcription, and the 3 major transcription steps.
How does DNA transcription work in bacteria and prokaryotes? In this lesson, we explain how bacterial transcription works and its 3 basic steps: initiation, elongation, and termination.
This lesson discusses the size scales relevant to cell biology.
The cell membrane is a mosaic and fluid structure. This lesson explains the factors that affect cell membrane fluidity, increase and decrease membrane fluidity of the phospholipid bilayer.
