How can and why do cells with the same genomes have different structures and
functions? Question 38
cell genome
same for every cell
different expression
heterochromatin
Histone modifying enzymes
Chrom rem complexes
euchromatin
alternative splicing
cell signaling
DNA regulation
Promoters
TATA box
inhibitors
effector cascade
Delta-notch pathway
Embryonal differenciation
post-translational modifications
lipidation
glycosilation
diff reactions w the same ligand
acetylcholine
salivary glands
muscle cells
heart
WHY?
cell differenciation
stem cells
totipotency, multipotency ecc
adult v fetal stem cells
genetic reprogramming
ligands can affect gene expression
contact inhibition
