What are some of the steps in eukaryotic transcriptional control? Multiple Choice OA transcriptional repressor recruits nucleosome remodeling proteins that alter nucleosome positioning, modification, and composition. This allows for the formation of a closed chromatin complex, and binding of general transcription factors and RNA polymerase II. Histone cores remain on the gene as transcript elongation […]

The rhombic lip lasts much longer in humans than it does in mice. If you were doing a BrdU experiment in mice and humans and you tested at 3 different stages, early in gestation, mid-gestation, and birth, where would you expect to see replicating cells in these two models and how would they be different?
