Question

If a cell has twice as much DNA as in a normal functional cell it means that the cell:

• A. Is preparing to divide
• B. has completed division
• C. has reached the end of its life span
• D. has ceased to function

Answer 1

The correct option is A

Is preparing to divide

The correct option is A:

Explanation of the correct option:

1. If a cell has twice as much DNA as a normal functional cell then it means that the cell will be going through the replication process.
2. Replication of DNA takes place before the dividing phase.
3. Replication takes place in the S phase.
4. It marks the preparation of a cell to divide itself.

Explanation of the incorrect option:

Option B:

After a cell has completed division, new cells will be formed, having an identical copy of the original DNA (not twice).

Options C and D:

When the cell is about to die or has died (ceased to function), DNA replication will not be taking place.

Final answer: If a cell has twice as much DNA as a normal functional cell it means that the cell is preparing to divide.
