Objective:
Four combinations of five neutral sequence changes at rs713040, rs10768683, rs7480526, rs7946748, and rs1609812 occurring in the human beta globin gene defined as frameworks have been reported in beta globin gene. Here we report for the frequency of these frameworks in thalassemia major patients of North Iran.
Methods:
Beta globin gene frameworks of 46 thalassemia major patients of North Iran were determined using Denaturing Gradient Gel Electrophoresis.
Findings:
All these frameworks called framework 1, 2, 3, 3a were present at the frequency of 23.9%, 45.7%, 6.5% and 23.9% respectively.
Conclusion:
These frameworks may be used for tracking mutant alleles in prenatal diagnosis programs.

02:21Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
