Some base sequences code for protein production. Some base sequences cause the release of lipids from the nucleus. Some base sequences contain the order of sugars in polysaccharides. Some base sequences produce electrical signals sent to the cytoplasm.
I gave my students this multiple choice question: Why is the particular sequence of bases in a segment of DNA important to cells?

Only one answer is correct among these 4 choices:
- Some base sequences code for protein production.
- Some base sequences cause the release of lipids from the nucleus.
- Some base sequences contain the order of sugars in polysaccharides.
- Some base sequences produce electrical signals sent to the cytoplasm.

Could you tell me which one is correct?
