Which example correctly matches polymer with monomer?

Correct answer: DNA is a polymer made from nucleotide monomers.. MCQ route 9: this exact option matches Define polymers as molecules made from many monomers joined together. and should be chosen over distractors that change the mechanism, context or biological consequence.

Reasoning route 9: The response earns credit when it separates the named process from its effect. Here the relevant objective is Define polymers as molecules made from many monomers joined together., so the explanation must stay specific. The correct option is "DNA is a polymer made from nucleotide monomers.", so the explanation must explicitly support that wording. The question wording is "Which example correctly matches polymer with monomer?". Distractors usually fail because they reverse the mechanism, use the wrong scale of organisation, or describe a related topic without answering the exact objective. If practical wording appears, address method, independent variable, dependent variable, control variables, risk, precision, accuracy and uncertainty; evaluate limitations, reliability, validity, anomalies and the conclusion. For aseptic or microbial work, include contamination control, sterile technique, disinfectant use or inhibition-zone evidence.
