Question

which of the following molecules are polymers?

monosac
rna
dna
amino acid
cellulose
lipid
polypeptide
atp

Answer 1

Among the molecules listed, the following are classified as polymers:

1. **RNA** - Ribonucleic acid is a polymer composed of nucleotide monomers.
2. **DNA** - Deoxyribonucleic acid is a polymer made up of nucleotide monomers as well.
3. **Cellulose** - This is a polysaccharide (a carbohydrate) that is a polymer made of glucose monomers.
4. **Polypeptide** - This is a polymer made up of amino acid monomers.

The other molecules listed are not classified as polymers:
- **Monosaccharide** - This is a single sugar unit and is not a polymer.
- **Amino Acid** - This is a single unit (monomer) and not a polymer by itself.
- **Lipid** - Lipids are generally not polymers, as they are composed of various building blocks (like glycerol and fatty acids) but do not form long repetitive chains.
- **ATP (Adenosine Triphosphate)** - This is a nucleotide and is not a polymer, although it is a building block for RNA and DNA.

So, the polymers from your list are RNA, DNA, cellulose, and polypeptide.
