Final answer:
The β-globin locus consists of genes spanning about 50 kbs, with each gene coding for the β portion of hemoglobin. The combination of globin and heme forms a functional hemoglobin protein. correct answer to the question is B
Step-by-step explanation:
The β-globin locus is a cluster of genes which spans about 50 kbs. Each gene codes for a protein that can form the β portion of hemoglobin. Therefore, the correct answer to the question is B) Genes, 50, β.
Hemoglobin is a protein composed of globin and heme, with the globin portion made up of two alpha (α) and two beta (β) polypeptide chains. Mutations in the β-globin genes can lead to diseases like sickle cell anemia and β-thalasemia, underscoring the importance of the precise amino acid sequence encoded by these genes. correct answer to the question is B
