Question

which molecule(s) sustain(s) an alteration due to the sickle cell mutation in the beta-globin gene?
beta-globin dna
beta-globin mrna
hemoglobin protein
beta-globin dna and hemoglobin protein
beta-globin dna, beta-globin mrna, and hemoglobin protein

Explanation:

Sickle cell mutation occurs in beta - globin DNA. DNA is transcribed to mRNA (so beta - globin mRNA is affected). mRNA is translated to protein (hemoglobin protein). So all three (beta - globin DNA, beta - globin mRNA, hemoglobin protein) are altered.

Answer:

beta - globin DNA, beta - globin mRNA, and hemoglobin protein
