The Formation of Nuclear and the Nuclear Envelope
Illustration 1 below shows a Cell with a Centrosome, and the Chromatin threads wrapped inside the Nuclear Envelope.
As already stated earlier, whatever change that occurs in nature, it certainly relates to the prevailing laws of nature. The emergence of Nuclear and the Nuclear Envelope is definitely no exception.
When oil is sprinkled on the surface of water, those drops of oil that are close to each other will soon be seen to gradually come together to form bigger drops. This is due to the cohesive nature of oil—provided such union is possible, of course, otherwise what happens is none other than that the particles of oil simply come closer or just stick to each other.
Similarly is the case with those Chromosomes wrapped in Protein. Being bonded and gathered together when the Cell divides, the Chromosomes continue to come closer to each other and remain concentrated, as exemplified by the oil, even after the division. Thus emerge Nuclear (see illustration 1). It is not at all an unusual sight to see tiny particles, by adhesion, stick to the edges of the accumulated drops of oil. This is very much similar to the formation of the envelope of Nuclear which in fact originates from those particles sticking to it.(illustration 3c). However, if one is to look into the nuclear envelope, one will instantly notice how complex the nuclear envelope of today is, particular when the picture appears in multifarious colours adorned with linear designs. In other words, with the Chromosomes held by the Centrosome, and with the continuous dismantling and recovery of the compounds, the Chromosomes, though they do shake, are yet unable to leave their surroundings because of their bonds. With the Chromosomes bonded to the Centrosome (at certain times) by the Microtubule, the shake that occurs causes the Centrosome to move randomly around such that they (the Chromosomes) eventually touch and stick to each other, and gather together to form a union.
It is perhaps necessary to remind here that since the movement of the Chromosomes is one that is evolutionary in nature, it therefore takes a long for them to be able to stick to each other. Of course, the shape they take are also subject to evolutionary changes too. That is why in illustration 3b the Chromosome is depicted as one that has already undergone a change. This is certainly a natural condition that needs no questioning.
