Question

15 multiple choice 1 point which statement describes an allele? a. a section of dna in which the code for a protein is located b. one variation of the code for a protein c. the pair of dna sequences an organism has for a trait d. the physical trait produced by an organisms genetic makeup

Explanation:

To solve this, we analyze each option:

• Option A: A section of DNA with protein - coding is a gene, not an allele.
• Option B: An allele is a variant form of a gene (which codes for a protein), so this describes an allele.
• Option C: The pair of DNA sequences for a trait is a genotype (homozygous or heterozygous), not an allele.
• Option D: The physical trait from genetic makeup is a phenotype, not an allele.

Answer:

B. one variation of the code for a protein
