In prophase of mitosis and meiosis ii homologous chromosomes do not form pairs in this way. Importantly homologous chromosomes pair up which is unique to prophase i. Centrioles start moving to opposite poles of the cell and a spindle begins to form.
The nuclear envelope begins to break down and the chromosomes condense. In mitosis the nuclear envelope break. Search for an answer or ask weegy.

In mitosis the nuclear envelope break down during prophase. Prophase definition the first stage of mitosis or meiosis in eukaryotic cell division during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. These thick chromosomes make dna more compact and easily moved within the cell.
Prophase is the time during which the dna in the nucleus condenses meaning it gets packaged by many proteins into thick finger like structures. The nuclear envelope breaks apart during prophase. Dna synthesis migration of centrosomes to opposite poles attachment to kinetochore microtubules to chromosome a change in cylinder concentration during g1 all the above during chromatids transition into chromosomes cytokinesis anaphase 5 phase metaphase.
If the nuclear envelope does not break down during a round of cell division it would prevent. During prophase chromatin condenses into chromosomes and the nuclear envelope the membrane surrounding the nucleus breaks down. Results from this system lead us to propose a new model for the mechanism of nuclear envelope breakdown in which nuclear pore disassembly has a central role.
It is also feasible to express exogenous proteins by mrna injection.
Nuclear envelope breaks down. The nuclear envelope also known as the nuclear membrane is made up of two lipid bilayer membranes which in eukaryotic cells surrounds the nucleus which encases the genetic material. The nuclear envelope consists of two lipid bilayer membranes an inner nuclear membrane and an outer nuclear membrane. The space between the membranes is called the perinuclear space. The gv breaks down 20 30 min after application of the maturation hormone 1 methyladenine 1 ma.
