DNA is just a junction for nucleic acid and it's the term nucleic that comes from the fact that it's found in the nucleus. It's found in the nucleus of eukaryotes. WebPerhaps the most likely place to find guanine quadruplex structures in nature is the telomere, or terminal region of linear chromosomes. These are composed of many repeats of the type G n T m, sometimes containing an adenine, A, adjacent to guanine (74, 75).This sequence is ideally suited to form either hairpin dimer or unimolecular quadruplexes. deworld import
