What term describes a long molecule made up of many similar or identical units?

• A. Monomer
• B. Polymer
• C. Micelles
• D. Macromolecule

Answer: (B)

The term that describes a long molecule made up of many similar or identical units is "polymer." Polymers are large molecules composed of repeating structural units known as monomers, which are chemically bonded together. These repeating units allow polymers to exhibit unique physical and chemical properties depending on their composition and structure. In nature, examples of polymers include proteins, which are made of amino acids, and nucleic acids like DNA and RNA, which are composed of nucleotide units. Synthetic polymers, such as plastics like polyethylene and nylon, are also made up of long chains of repeating monomer units. Understanding this concept of polymers is crucial in biology and chemistry, as it helps explain the structure and function of many biological macromolecules essential for life processes.
