The ability to produce recombinant DNA molecules has not only revolutionized the study of genetics, but has laid the foundation for much of the biotechnology industry. The union can be made permanent by another enzyme, a DNA ligase, that forms covalent bonds along the backbone of each strand. If sticky ends exist on the fragment from the backbone, they must also exist in the fragment from the insert and vice versa. palindromic sequences: nucleic acid sequences where the one strand matches its complementary strand when read in the same direction. Each BamHI subunit makes the majority of its backbone contacts with the phosphates of a DNA half site but base pair contacts are made between each BamHI subunit and nitrogenous bases in the major groove of the opposite DNA half site. cystic fibrosis results from a three base deletion in most cases but in other cases, other mutations are involved.
