M-brane theory is significant in understanding the fundamental nature of the universe because it proposes that our universe may exist as a higher-dimensional membrane, or "brane," within a larger multiverse. This theory offers a potential explanation for the existence of multiple dimensions and could help unify the laws of physics.
If the membrane did not indent and pinch off during cell division, the two resulting daughter cells would not separate properly. This could lead to abnormal cell division, potentially causing developmental issues, cell death, or the formation of a multinucleated cell.
After chromosomes condense during cell division, they align along the center of the cell during metaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, during telophase and cytokinesis, the cell divides into two daughter cells, each with a complete set of chromosomes.
