Question

suppose this hose reel system were used to model a dna molecule, a chromosome, and a gene. which part of the model would best represent a dna molecule? a. the reel holding the coiled - up hose b. a specific section of the hose c. the entire length of hose d. the entire hose and reel system

Explanation:

A chromosome is a structure that contains DNA. A gene is a segment of DNA. The entire DNA molecule can be thought of as the whole - length of the hose, with genes being specific sections of it and the chromosome being the organized structure that contains it all. The reel is not part of the DNA equivalent in this model.

Answer:

C. The entire length of hose
