Question

In the human globin gene family, there is a single regulatory region where?

Answer 1

The regulatory region in the human globin gene family is called the promoter region. Mutations in the promoter region can lead to low levels of hemoglobin.

Step-by-step explanation:

In the human globin gene family, the regulatory region is called the promoter region. The promoter region is located upstream of the coding sequence of the gene and is responsible for initiating the transcription of the gene into mRNA.

Mutations in the promoter region can disrupt or reduce the binding of transcription factors, which are proteins that regulate gene expression. In the case of beta-thalassemia, mutations in the promoter region of the beta-globin gene can lead to low levels of hemoglobin, resulting in anemia.
