Question

1.1.4 quiz: chromosomes and dna
which part of the model would best represent a chromosome?
a. the entire hose and reel system
b. the entire length of hose
c. a specific section of the hose
d. the reel holding the coiled - up hose

Explanation:

A chromosome consists of tightly coiled DNA (the hose) along with proteins that help package the DNA, analogous to the reel organizing the coiled hose. The entire hose and reel system represents the chromosome: the hose is the long DNA molecule, and the reel represents the structural proteins that condense the DNA into the compact chromosome structure. The hose alone is just DNA, a section of hose is a gene, and the reel alone is only the structural component, not the full chromosome.

Answer:

A. The entire hose and reel system
