Both mitosis and meiosis are preceded by

Step 1: Define the Problem

Identify the key components of the question that need to be addressed: The question asks what process occurs before both mitosis and meiosis.

Step 2: Break Down the Problem

Divide the problem into smaller, manageable parts:

• Understand the stages of cell division.
• Identify the common stage that occurs before both mitosis and meiosis.

Step 3: Apply Relevant Concepts

Use appropriate academic theories or formulas to solve each part of the problem:

• Both mitosis and meiosis are types of cell division.
• Before either process begins, the cell undergoes a preparatory phase.

Step 4: Analysis, Verify and Summarize

Analyze each part in detail if necessary, carry out the calculations by steps. Verify the calculations result and summarize the findings:

• The preparatory phase before both mitosis and meiosis is known as interphase.
• During interphase, the cell grows, duplicates its DNA, and prepares for division.

Final Answer

Both mitosis and meiosis are preceded by interphase.
