    An original TEAS 7-style science practice question, written for nursing-school applicants — with a full breakdown of every answer choice.

    Question

    What term describes different forms of the same gene?

    • A.Alleles
      Correct
    • B.Chromatids
    • C.Ribosomes
    • D.Enzymes

    Correct answer: A. Alleles are alternative versions of a gene found at the same locus on homologous chromosomes.

    Why A is correct

    Alleles are alternative versions of a gene found at the same locus on homologous chromosomes.

    How to solve this TEAS question

    Identify what the question is testing, eliminate choices that conflict with the relevant rule or evidence, and then select the option that directly answers the prompt.

    Review the alternatives

    The other choices do not satisfy the scientific fact, mathematical operation, language rule, or reading evidence tested by this question. Always compare each option with the exact wording of the prompt before deciding.

    Quick study tip: Think of alleles as gene variants.
