mitosis
The biological catalyst that blocks a step in the separation of chromosomes would directly affect the process of cell division, specifically the phase of mitosis called anaphase. This disruption would prevent the chromosomes from properly segregating and result in improper distribution of genetic material to the daughter cells.
The cellular process directly affected by this catalyst in marine sponges is cell division, specifically during mitosis. The blockage of chromosome separation during cell division would disrupt the proper distribution of genetic material to daughter cells, leading to abnormal cell division and potential genetic mutations.
The cellular process that would be directly affected by a catalyst is typically a metabolic reaction, such as cellular respiration or photosynthesis. Catalysts, like enzymes, speed up these biochemical reactions by lowering the activation energy required, thereby increasing the rate at which substrates are converted into products. This acceleration can significantly impact energy production, nutrient processing, and overall cellular function.
The organelles crucial for these processes are the centrioles, which help in organizing the microtubules involved in chromosome separation, and the endoplasmic reticulum and Golgi apparatus, which are involved in cell elongation and membrane biogenesis during cellular reproduction.
Canadian and British researchers have discovered that chromosomes play an active role in animal cell division. This occurs at a precise stage - cytokinesis - when the cell splits into two new daughter cells.In animal cells, division involves mitosis, the separation of chromosomes followed by splitting of the cell into two new daughter cells by cytokinesis. "Division is a complex and robust process that is generally performed flawlessly, but when an error occurs in DNA separation or during cytokinesis, it can be a source for triggering cancer, for example," said Hickson.

During meiosis, tetrads, which are connected by a synapse partway down their length, line up along the cellular equator during metaphase I. The tetrads are then separated during anaphase I as the spindle fibers pull the tetrads apart towards opposite sides of the cell.

During the production of Gametes, a meiotic non-disjunction can occur meaning the faulty separation of the chromosomes. The 21st chromosome is copied twice into the new cell and when this meets its corresponding gamete, it creates an embryo with cells with 47 chromosomes, rather than 46.

M [mitosis]-phase follows both Growth-phase 1 and [dna synthesis] S-phase; the transition between S-phase and M-phase involves the condensation of chromatin into chromosomes, and what is frequently observed is the movement, translocation, separation [division] and migration of the two sets of chromosomes to the two Cellular/nuclear 'poles'. This is very quickly followed by Cellular binary fission.
