Question

multiple answer 1 point
click all of the following that are nucleic acids

Explanation:

To determine which are nucleic acids, we recall: Nucleic acids (DNA, RNA) are polymers of nucleotides (phosphate, sugar, base). Proteins are amino acid polymers, carbohydrates (mono/polysaccharides) are sugar - based, and lipids are hydrophobic.

1. The first image (DNA double helix) is DNA, a nucleic acid.
2. The second image is an amino acid (protein monomer), not a nucleic acid.
3. The third image is a polysaccharide (carbohydrate), not a nucleic acid.
4. The fourth image is a protein (3D structure), not a nucleic acid.
5. The fifth image is a monosaccharide (carbohydrate), not a nucleic acid.
6. The sixth image is a lipid (phospholipid), not a nucleic acid.
7. The seventh image is a lipid (triglyceride - like), not a nucleic acid.
8. The eighth image is a nucleotide (monomer of nucleic acids), and nucleic acids are made of nucleotides, so this is related to nucleic acids (and the DNA structure above is also nucleic acid).

Answer:

The first checkbox (DNA double helix) and the eighth checkbox (nucleotide structure: Phosphate, Sugar, Base) should be clicked. (If we consider DNA as a nucleic acid and nucleotides as the building blocks, so the first (DNA) and the eighth (nucleotide) are nucleic - acid - related. Also, RNA would be similar, but in the options, the DNA structure and the nucleotide are the nucleic - acid - containing ones. So the correct checkboxes are the first (with the DNA helix) and the eighth (with Phosphate, Sugar, Base).)
