Although each cell contains a copy of all the genes of that genome, certain genes are:
Correct answer: B. Turned off in mature specialized cells
- A. Amplified in mature specialized cells
- B. Turned off in mature specialized cells
- C. Lost in mature specialized cells
- D. Mutated in mature specialized cells
Explanation
When a cell is assigned a specialized job, only those genes remain active which are associated with that particular job, rest are turned off, however, they can be switched on again if needed.
