polyspermy उदाहरण वाक्य

उदाहरण वाक्य

1. This sees the release of cortical granules that release enzymes which digest sperm receptor proteins, thus preventing polyspermy.
2. Researchers have suggested that calreticulin serves as a chaperone protein for other cortical granule components contributing to polyspermy prevention.
3. In sea urchins, the block to polyspermy comes from two mechanisms : the fast block and the slow block.
4. The "'cortical reaction "'is a process initiated during slow block of polyspermy in many animals.
5. Additionally contributing to polyspermy prevention, calreticulin may also inhibit certain glycoproteins, which promote interaction between the oocyte and sperm.
6. In species without an electrical block, polyspermy is usually prevented by secretion of materials that establish a mechanical barrier to polyspermy.
7. In species without an electrical block, polyspermy is usually prevented by secretion of materials that establish a mechanical barrier to polyspermy.
8. Triploidy, usually due to polyspermy, occurs in about 2 3 % of all human pregnancies and ~ 15 % of miscarriages.
9. The prevention of polyspermy in sea urchins depends on a change in the electrical membrane is repelled by the positive charge at the egg surface.
10. The released hyalin modifies the extracellular matrix of the fertilized egg to block other sperm from binding to the egg, and is known as the slow-block to polyspermy.
