What is the specific cellular process for regulating the amount of the four DNA bases (adenine, thymine, cytosine, and guanine) that are present in the cytoplasm of a cell?
Basically, how do the cell's mechanical processes "know" that there are enough of these present in the cytoplasm for DNA/RNA processes to operate effectively?
From what I understand, DNA/RNA sequence production involves simply grabbing these out of the cytoplasm as they randomly pass near the sequence assembly protein.
As a side topic, but also important here, the cytoplasm is apparently just a random fluid containing all sorts of molecules flowing and diffusing in random directions via Brownian motion. I do not know if there is a specific direction cytoplasm flows around the inside of a cell, and if so, how the cell would manage to coordinate that either.
There does not seem to be a way for cell processes to "read" the proportional molecular contents of the cytoplasm to know if there is sufficient numbers of these present for proper cell function.
If there is a lack of any one of these four base molecules, DNA/RNA processes will slow or stop functioning, leading to systemic failure and potentially cell death.
If there are too many of any one of them, the cell could become so packed that nothing can move around and the cell's function is impaired. Possibly the cell wall could rupture if there are too many.
