the machinary required to sperate the sister chromotids (each set of DNA) is outside the nucleus, and therefore requires access to the DNA. also the nucleus is quite small, so allowing the DNA access to the rest of the cell allows for more separation (i.e. a greater distance between the two sister chromotids can be acheived).
Cellular Division.
in early stage of mitosis
The nuclear membrane begins to fade from view during prophase, which is the first stage of mitosis. As the cell prepares for division, the nuclear membrane breaks down to allow the chromosomes to move freely within the cell.
The Nuclear membrane dissolves during prophase
The nuclear membrane fades during the prophase of mitosis or meiosis. This is the stage when the membrane begins to break down and disappear, allowing the chromosomes to become more condensed and accessible for cell division.
True. The nuclear membrane disintegrates during prophase of mitosis to allow the condensed chromosomes to be visible and function properly during cell division.
prophase
Cellular Division.
Prophase
The nuclear membrane reforms during late telophase of mitosis or meiosis, while the nucleolus reappears during interphase.
The phase of mitosis that begins when the nuclear membrane starts to fade is called prometaphase. During prometaphase, the nuclear membrane breaks down, allowing the spindle fibers to attach to the chromosomes.
Mitosis Prophase. Yep one homework question answered!
in early stage of mitosis
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
The major one is replication of the genetic material.
The nuclear membrane is reformed during the telophase stage of mitosis or meiosis. This process involves the reassembly of the nuclear envelope around the separated daughter chromosomes to form two distinct nuclei in each daughter cell.
