A. The transposable elements are “dead” because they are only found in non-coding regions and therefore do not interfere with phenotypic expression. B. The transposable elements are “dead” because they are no longer able to undergo transposition and move to another region of the genome. C. The transposable elements are “dead” because they do cause disease despite their presence. D. The transposable elements are “dead” because they occur only in somatic cells and therefore are not heritable.arrow_forwardinvolved in the transfer of multiple drug resistance from one cell to another? * a.Transposition b.
