Question

which best describes a gene?
○ the short arm of a chromosome
○ tightly coiled strands of dna
○ the center of a chromosome
○ a segment of chromosomal dna

Explanation:

• The short arm of a chromosome is called the p-arm, not a gene.
• Tightly coiled strands of DNA make up chromosomes, not genes specifically.
• The center of a chromosome is the centromere, not a gene.
• A gene is defined as a specific segment of chromosomal DNA that codes for a functional product (like a protein or RNA).

Answer:

a segment of chromosomal DNA
