Final answer:
The statement is false; DNA consists of two polynucleotide chains, not a single chain, forming a double helix. Nucleotides serve as the monomers for DNA and RNA polymers.
Step-by-step explanation:
DNA molecules, unlike proteins, do not consist of a single long polymeric chain that is assembled from small monomeric subunits.
This statement is false. DNA molecules are composed of two long polynucleotide chains that twist around each other to form a double helix structure.
In contrast to this, proteins are long chains of amino acids, making them essentially single polymer chains, albeit often folded into complex three-dimensional structures.
DNA and RNA are polymers made up of repeating units called nucleotides, which are monomers, and these nucleotides include a phosphate group, a five-carbon sugar (deoxyribose for DNA and ribose for RNA), and a nitrogen-containing base.
The sugars and phosphate groups form the backbone of the DNA or RNA polymer, while the nitrogen bases are responsible for the genetic coding.
