Barbara mcclintock discovered mobile elements in corn by analyzing the genetic behavior of two elements, ds and ac. the interplay between these two elements has become one of the most interesting stories of discovery in the field of genetics. how do ds and ac interact

Barbara McClintock was the first who discovered mobile elements (transposons) by recognizing the breakage that occurred at specific sites on corn chromosomes. The first element she discovered was a site of the chromosome breakage and she called it Ds (“dissociation”). Then, she noted that the movements of Ds are regulated by another autonomous element which she called Ac ("activator"), which can also promote its own transposition.
