Question

In certain types of cells, like liver and heart tissues, tetraploid cells are normal and common. However, sometimes the formation of tetraploid cells may be an unintentional result of exposure to chemicals or other factors. These rogue tetraploid cells may eventually lead to tumor formation. These cells most likely form due to a failure at which phase of the cell cycle?

Answer 1

Answer:

Cytokinesis

Explanation:

Cytokinesis is the last phase in cell division.

It is a well ordered stage, that needs a detailed interaction between cytoskeletal, chromosomal and cell cycle regulatory pathways. An astonishing wide amount of certain cellular activities are also essential for cytokinesis, inclusive of protein and membrane interaction, lipid metabolism, protein synthesis and signaling pathways.

As a largely controlled, complex phase, it is not unforeseeable that cytokinesis often times fail. Cytokinesis failure will cause centrosome amplification and formation of tetraploid cells, which cause the formation of tumor cells. Thou, tetraploid cells are rich components of some typical tissues such as liver and heart, signifying that cytokinesis is physiologically controlled.

Answer 2

These cells most likely form due to failure at cytokinesis phase of the cell cycle

Phases of cell division

Cell division in organisms occur in six( 6 ) phases before the cell will undergo a complete cell division process. the phases of cell division are

• Prophase
• Prometaphase
• Metaphase
• Anaphase
• Telophase
• Cytokinesis

The cytokinesis is the last phase and the formation of tetraploid cells is due to the failure of the cell division process at the cytokinesis stage which is last stage of physical division of cells.

Hence we can conclude that These cells most likely form due to failure at cytokinesis phase of the cell cycle
