- LDL receptor can't bind LDL
- LDL receptor binding reduced
- LDL receptors incapable of bringing cholesterol into cell after binding (internalization)
A blastomere (Individual cells) is formed when a zygote undergoes multiple mitotic divisions (cleavage) within the zona pellucida.
At the 5th cleavage the blastomeres form a morula. The morula enters the uterine cavity.
Morula undergoes cavitation and forms the blastocysts (inner and outer cell mass) at this time the zone pellucid is dissolved
