Multiple Choice

Why is gene regulation at the molecular level significant for living organisms?

1

It allows organisms to adapt to environmental changes by controlling gene expression.

2

It prevents all genes from being expressed at once, saving energy and resources.

3

It enables cell specialization and development of complex tissues.

4

All of the above.
