Question

The various phases of the cell cycle will be affected by limiting growth factors like

• A. Sufficient nucleotides
• B. Temperature
• C. Nutrients
• D. All of the above

Answer 1

Answer: (D)

All of the above

• Different phases of the cell cycle will be affected by limiting growth factors such as nutrient supply, temperature, and room for growth.
• Sufficient nucleotides and amino acids must be present in order to synthesize mRNA, proteins and to replicated DNA.
• Physiological temperatures are optimal for cell growth so that enzymes involved in the cell cycle can work efficiently. In humans, the normal physiological temperature is around ${37}^{0}C$.

Therefore, the correct answer is option D.
