Question

complete the table to compare the structures of a lipid and dna.
lipid\tdna
has hydrogen bonds between nitrogenous bases\t○\t○
has two strands of nucleotides joined together\t○\t○
forms a double helix\t○\t○
submit

Explanation:

To solve this, we analyze the structures of lipids and DNA:

For "Has hydrogen bonds between nitrogenous bases":

• Lipids: No (lipids don’t have nitrogenous bases).
• DNA: Yes (adenine - thymine and cytosine - guanine pairs are linked by H - bonds).

For "Has two strands of nucleotides joined together":

• Lipids: No (lipids are not made of nucleotides).
• DNA: Yes (DNA is a double - stranded nucleic acid with nucleotide strands).

For "Forms a double helix":

• Lipids: No (lipids have structures like fats, phospholipids, etc., not a double helix).
• DNA: Yes (DNA has a characteristic double - helix structure).

Feature	Lipid	DNA
Has two strands of nucleotides joined together	No	Yes
Forms a double helix	No	Yes

(For the table in the problem, mark "No" for Lipid and "Yes" for DNA in each row as per the above analysis.)
