Study Notes
Oogenesis and Embryonic Development
- During oogenesis, Staufen protein is responsible for setting up cytoplasmic polarity.
Gene Regulation and Expression
- The bicoid gene is responsible for determining the positions of gap genes.
Embryonic Pattern Formation
- The transcription factor protein Dorsal is present in the ventral side of the embryo.
Signaling Pathways
- The protein Toll represses the Zen pathway.
Gene Activation and Expression
- The gene twist is activated by Dorsal and is only present in most FGF and Riddle/Palmeirim cells.
Test your knowledge on oogenesis, cytoplasmic polarity, and gene expression in this quiz. Learn about the role of Bicoid and Nanos in setting up cytoplasmic polarity, the expression of genes post-fertilization, and the impact of Dorsal on DV patterning.
