Dissappearance of the Nuclear Membrane

[Conceptual]

The disappearance of the nuclear membrane after the DNA condenses into chromsomes is an anomoly can be explained with hydrogen bonding. When the nuclear membrane goes from a large single structure into many smaller subunits, so it can disperse, the effect is due to surface tension with the nucleus of the cell.

 

The increased surface tension within the nuclear membrane is directly related to the condensed chromosomes. Condensed chromosomes are the highest hydrogen bonding potential structures within the entire cell cycle. These increase the hydrogen bonding potential within the nucleus water and thereby increase the hydrogen bonding potential within the nuclear membrane. The result is increased surface tension to make more nuclear membrane surface area.

 

The connection between hydrogen bonding potential and surface tension is actually quite simple. When water is in contact with hydrophobic materials, aqueus hydrogen bonds can not form. This increases the hydrogen bonding potential of the water. The reverse is also true, if the hydrogen bonding potential of the water is induced locally high, in this case by the condensed chromosomes, the surface tension defined within the nucleus water and by the local structures are induced to increase.

For the love of all that is holy, not everything involves hydrogen bonding. The dispersal and reformation of the nuclear envelope is due to phosphorylation of the nuclear lamina, as web of intermediate fillaments holding it together.

 

There is *nothing* to suggest that chromosomes are any significantly more polar of prone to hydrogen bonding than anything else.

 

If you can't be bothered to open a book and read, don't just concoct wild theories instead.

Those changes within the nuclear membrane are equilibrium phenomena connected to hydrogen bonding potential. The DNA defines high hydrogen bonding potential, in part, due to every base pair having an extra hydrogen bonding hydrogen thay does not form. The packing proteins or histones are rich is residues with many hydrogen bonding hydrogen. When the DNA condenses into chromosomes, a relatively high hydrogen bonding potential molecule (DNA) is packing with very high hydrogen bonding potential histones. The result is very large composites that define very high hydrogen bonding potential. These composites are dissolved in water and thereby conduct this hydroge bonding potential into the aquoeus hydrogen bonding potential of the nucleus water. The change in the nuclear membrane only happens at this time. Is this cooincidental?

[Mokele]

Just because two things co-occur does not mean they are causally related.

[zyncod]

The hydrogen bonding potential is actually *lower* in condensed chromosomes than that in interphase chromosomes since the bonding to histones and a lot of the higher order condensation structures uses hydrogen bonds from the DNA phosphates or sugars.
