Question
what organizes and pulls cells apart
Answers
GPT-4o mini
In the context of cell division, particularly during mitosis and meiosis, the structure that organizes and pulls cells apart is the **spindle apparatus**. The spindle apparatus is made up of microtubules, which are dynamic protein filaments that originate from the centrosomes (also known as microtubule-organizing centers) located at opposite poles of the cell.
During cell division, these microtubules attach to the kinetochores (protein complexes on the centromeres of chromosomes) and help segregate the sister chromatids (or homologous chromosomes, in the case of meiosis) into the daughter cells by pulling them towards opposite poles. This ensures that each new cell receives an identical set of chromosomes.
In summary, the spindle apparatus organizes and pulls the chromosomes apart during cell division, aiding in the distribution of genetic material to the daughter cells.
