What is a sequence of DNA responsible for a characteristic in an organism?

• A. Allele
• B. Genome
• C. Gene
• D. Chromosome

Answer: (C)

A gene is a specific sequence of DNA that contains the instructions to make a product (usually a protein or RNA) that influences a particular characteristic. Because this sequence directly governs how a trait develops, it’s the basic unit responsible for that trait. Alleles are just different versions of the same gene, which can lead to variation in the trait. The genome is the entire set of genetic material, and a chromosome is a structure that carries many genes. So the DNA sequence that determines a trait is a gene. For example, a gene involved in pigment production can influence eye or hair color, and different alleles of that gene can yield different colors.
