Cytokinesis Original Scenario-Based Practice

Questions

1. 1.

   In an advanced xenobiology laboratory, synthetic biologists design a bio-robotic nanite to observe dividing plant-like cells isolated from a deep-sea hydrothermal vent organism. The nanite records that mitosis completes normally with distinct daughter nuclei reforming at opposite poles, but the transport and coalescence of Golgi-derived vesicles along the equatorial plane are entirely blocked. Consequently, the dividing entity fails to build a partitioning wall and forms a single cell containing two distinct nuclei. Which stage of the cell division cycle was directly impeded in these engineered organisms?

   • A) Metaphase chromosome alignment along the spindle equator
   • B) Cytokinesis mediated by the formation of a cell plate
   • C) Anaphase separation of sister chromatids toward spindle poles
   • D) Telophase reformation of the surrounding nuclear envelopes
