Question

what is dna? why is it important?
it is a molecule made of nucleic acids, it tells the cells how to make proteins
it is a molecule made of nucleic acids, it makes energy for the cell
it is a molecule made of lipids, it tells the cells how to make proteins
it is a molecule made of lipids, it makes energy for the cells
question 3
dna is found in the nucleus of eukaryotic cells and the ______ in prokaryotic cells. this is because prokaryotic cells do not have a nucleus.
cytoplasm/cytosol
nucleus

Explanation:

• DNA is a nucleic acid molecule. It contains the genetic instructions for protein synthesis. Lipids are a different class of biomolecules (e.g., fats, oils) and do not carry the genetic information for protein - making. Also, DNA does not directly make energy for the cell (processes like cellular respiration do that).
• Prokaryotic cells lack a nucleus. In prokaryotes, DNA is located in the cytoplasm (or cytosol). Since prokaryotes have no nucleus, the option “nucleus” is incorrect.

Answer:

• First question: It is a molecule made of nucleic acids, it tells the cells how to make proteins.
• Second question: cytoplasm/cytosol.
