The FALSE statement is that the cell cycle control system operates independently of the growth factors (Option 1).

  • A cell cycle refers to the processes that occur in a cell as it grows and divides into two daughter cells.

  • The cell cycle can be divided into an interphase (no division stage) and division stage (either mitotic or meiotic cell division).

  • The growth factors are proteins that have fundamental roles in the regulation of cell division.

  • These proteins (growth factors) can promote or blocks cell division.

  • Some examples of growth factors include Epidermal growth factor (EGF), Platelet-derived growth factor (PDGF), Vascular endothelial growth factor (VEGF), Erythropieitn, etc.

In conclusion, the FALSE statement is that the cell cycle control system operates independently of the growth factors (Option 1).
