DNA cloning

1- The genes for both the alpha-and beta-globin chains of hemoglobin contain introns (i.e., they are split genes). How would this fact affect your plans if you wanted to introduce the gene for alpha-globin into a bacterial plasmid and have the bacteria produce alpha-globin?

2- Bacteria and yeast are known not to have prions. What does this fact have to do with the popularity of expressing mammalian proteins using bacterial vectors?

1. Bacteria are unable to process introns therefore in order to express alpha-globin in a bacterial cell the introns must be removed ...
