biochem - 25hydroxylase - ArchivalUser - 12-04-2008 . Beta-Thalassemia results in the reduction of beta chains of hemoglobin due to errors in the processing of the initial mRNA transcript. The mechanism is most likely to involve a single nucleotide change in which of the following? A. AUG start codon B. Enhancer element in the first intron C. Splice site D. Termination codon E. Upstream promoter element 0 - ArchivalUser - 12-04-2008 c 25 - ArchivalUser - 12-04-2008 explain 0 - ArchivalUser - 12-04-2008 Reduction of beta chains in the haemoglobin result on mutation of a protein through splice sites and splicing of beta globin mRNA are responsible for few cases of beta thalassemia.... |
