AI Thread Summary
As cells age, their nucleus tends to shrink, leading to a decrease in the nuclear-to-cytoplasmic (N/C) ratio, which typically shifts from 4:1 to 2:1. This change is associated with a decline in cellular machinery efficiency and organization. A high N/C ratio is often indicative of cancerous cells, suggesting that cancer cells maintain a larger nucleus relative to their cytoplasm. Mitosis plays a crucial role in regulating the N/C ratio, ensuring that cells can maintain proper function as they divide. References supporting these claims include Wikipedia for the N/C ratio and cancer characteristics, Guyton and Hall's Physiology for cellular organization, and NCERT's 12th Standard Biology for the role of mitosis in N/C maintenance.

TL;DR Summary
My question is 'If the normal Nuclear:Cytoplasmic Ratio of a cell is not maintained then what happens?'
From Wikipedia I have found out that as a cell ages, it's Nucleus shrinks and thus the intial N/C decreases from 4:1 for most cells to 2:1.
I also have a rough idea that Cell machinery becomes unorganised and inefficient.Also high N/C is a characteristic of Cancerous cell.But I do not know the exact reasons.
Finally Mitosis is a direct response to maintain N/C.
Please elaborate more...

It looks like your ratio may be backwards:
N/C = 4:1 would mean the nucleus is larger than the cell that houses it.

Please provides links or references for your several claims:
"as a cell ages, it's Nucleus shrinks"
"unorganised and inefficient"
"high N/C is a characteristic of Cancerous cell"
"Mitosis is a direct response to maintain N/C"

👆🏽This link is the reference for the 1st and 3rd claims.
2nd Claim is supported by Guyton and Hall's book of Physiology(which says that the nucleus faces difficulty in controlling it's intercellular proteins)
4th claim is supported by 12th Standard Biology book (NCERT).

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
