The Direction of the Division
What is it that compels the cell-to-be to rotate during its division?
Illustrations 1 and 2 is a 3-dimensional representation of the direction the cell-to-be takes during its division. Here the cells-to-be are shown to be undergoing division, naturally, for the first time. X1 and X2 represent the cores of the newly formed cells-to-be resulting from the division of the core of cell-to-be X. The positions of X1 and X2 are represented by the two black dots which are simultaneously the points at which the horizontal line(h) and the vertical line (v) intersects each other perpendicularly.
The figures depicting the various angles serve merely as examples.
Because when dividing itself a certain angle is formed between the axis of the perfect division and the direction it takes in the division (the broken line), the cell-to-be therefore rotates.
Even if it so happens that its “twin sister” is in the axis of the perfect division—though the possibility is very slight—it will still rotate if the vertical lines are not perfectly parallel.(see illustrations 4 and 5).
What is it that has caused the cell-to-be to inevitably rotate during its division? Every division that goes in a direction other than the one shown by the arrow (see Illustration 3), must certainly result in a rotation, no matter how small the angle it forms is. So incredibly small is the possibility for the cell-to-be to rotate in a direction precisely following that of the arrow that one may perhaps be justified in saying that such idea of precise rotation would just be out of the question. It must somehow rotate away from the direction pointed by the arrow. It is this very direction that will in its later division indirectly influence the various components in the body of the cell-to-be. Thus it is natural that the directions taken by the two newly formed “daughter cells”—the result of the division of the “mother cell”—are not the same.(illustration 2). This certainly holds true until today.
Perhaps there are those among the readers who are just skeptical about this. “How could it be that those cores, which in the illustration are obviously in one straight line, couldn’t have been as such in reality?” they may wonder. Also when one looks at illustration P under the heading Impossibilities and Possibilities, it will instantly occur to one how easy it is for anyone to draw such straight line. So what is it then that has in reality made it impossible for the cores to be in a straight line? Isn’t it oftentimes implied that no matter how miniscule a possibility is, the opportunity is always open for it to be a reality? This makes sense indeed for all else, but not for the cell-to-be, which in its journey during division, i.e. from the time it starts to divide through to the time it totally splits up, has been undergoing lots of shakes in different directions, though such changes of movements may only be a few Angstrom. (see illustration 4). The shakes meant here are the ones that occur when the split-up parts are being pushed away from each other by the various dismantling of compounds occurring inside them—one seemingly pushing the other to the left then to the right and so on. It is this that makes them experience a torque, though actually they do have the ability achieve a line as straight and accurate as is shown in illustration 5. Although the vertical and the horizontal lines of the “daughter” cells-to-be for an angle, the torque power will continue to exist. This will still cause both “daughters” cell-to-be to form an angle with each other or to move around each other.
Thus, two things explain why both parts move around each other: firstly, at the time division takes place, the imaginary vertical and horizontal lines of each of the two “daughter” cells-to-be form an angle with the other; secondly, both of them rotate because they experience torque.
This is the reason why each separated “daughter” cell-to-be must form an angle with the other, and why each has its internal parts (the DNA-to-be and the Microtubule-to-be) twisted.
Why is it that only some parts of the cell-to-be rotate?
Following is a bit of additional information meant to enable the readers to envisage what is it that actually initiates such rotation. In illustrations 6, 7, and 8 an attempt is made to explain about the direction of the division and the occurrence of the rotation. In illustration 9 the orange arrow shows the direction of the division of the “daughter” Cell in a position where it is almost completely divided. In the meantime, the tip of the microtubule and the DNA-to-be are also in that position, though they are inside the Cytoplasm-to-be (green).
Illustration 10 depicts the condition of the “daughter” Cell just a few moments after it is completely separated from its twin sister. The orange line is seen to be drooping, while at the same time trying to keep pulling itself (as shown in illustration 11). The orange line is envisaged to be the Microtubule-to-be and the DNA-to-be, both of which have just detached when the Cell-to-be completely divides itself into two. When, soon after this, the “daughter” Cell re-multiplies the inner part of its body, the movements involved in the process looks like twists, which after continuous division and multiplication, will appear to follow the route taken by the orange arrow from that point as shown in illustration 11 to that point as shown in illustration 10. The direction of the arrow is further clarified by the brown arrow.
Thus, any addition to the substances already existing in the Microtubule-to-be or in the DNA-to-be will follow the course taken by the brown arrow as is shown in illustration 11, and then, in a circular movement, this addition will follow the course taken by the brown arrow as shown in illustration 10,
Why is it so? Certainly, the re-addition and re-multiplication of whatever that exists inside the cell will begin only after the process of division is totally completed. The position of the cell when it divides for the last time is as shown in illustration 11. It is here where the re-multiplication of all substances begins (see illustration 12).
To further clarify the explanation above, we have below provided illustrations in which the area close to the core is enlarged (that part of illustration 11 facing illustration 10)
Illustration 12 is an enlarged version of illustration 11, which shows the condition of the central part/centre; illustration 13 is an enlarged version of illustration 10, which shows the condition of the central part/centre.
In the multiplication of the body substances chemically, the cell-to-be, serving as the “mother”, will divide again, which means that the direction and the angle of the division will be followed. Illustrations 15, 16, and 17: the movement is twisted as in illustration 18. That’s why everything, particularly the DNA and the Microtubule, is twisted.
Below is a more detailed explanation as to why that DNA-to-be and Microtubule-to-be are twisted.
Because the tips of the Microtubule-to-be and the DNA-to-be were parts that were situated in the middle of the Cell-to-be and that got detached last of all, they are thus the ones that feel the influence of the twists most (see illustrations above). At the edges of the Cell-to-be were the Cytoplasms-to-be, the part that got detached last of all when the division of the cell-to-be occurred.
Since the tip is the part that is most difficult to get detached in the first dismantling of the compounds of the DNA-to-be, it is therefore also influenced by the twists. Similarly is the case with the Microtubule-to-be. The greater the mass of the cell’s-to-be body is, the less will it be influenced by the twists.
Here we could see that while the twists of the DNAs and the microtubules were likely to occur at their rows of molecules when they formed an angle with each other, yet it had always been the angle of the division that had played a determinative role. That is why the DNAs and the microtubules, particularly those in the end position of the initial division (similar to the cytokinesis of today’s cell), were also affected and received many of the consequences of the division.
