pronucleus การใช้

• The sperm contributes a pronucleus and a centriole to the egg.
• We microinject it into the pronucleus in the egg yolk,
• After plasmogamy, the microtubule plus ends continue to grow towards the opposite pronucleus.
• The sequence in inserted directly into the pronucleus.
• The sperm's tail and mitochondria degenerate with the formation of the male pronucleus.
• A major consequence of CI is the delayed entry into mitosis of the male pronucleus.
• After the first stage of meiosis, the pronucleus fuses with its sister polar nucleus, thus restoring the correct number of chromosomes.
• The nucleus of the oocyte is called a pronucleus in this process, to distinguish it from the nuclei that are the result of fertilization.
• It is thought that the growing plus end of the microtubule attaches directly to the motor protein of the opposite pronucleus, triggering a reorganization of the proteins at the half-bridge.
• Identical twins develop after a single maternal pronucleus and single paternal pronuceus have formed a zygote, the zygote undergoes mitosis, and the daughter cells each develop into separate individuals .-- Seejyb 23 : 07, 12 August 2006 ( UTC)
