   Author : Samuel Jorayev; [2023]
   Keywords : Spok genes; FuSpok; Meiotic Driver; Fusarium; transposons;

   Author : Aleksei Põlajev; [2018]
   Keywords : lactobacillus kunkeei; transposon; transposase; mobile genetic element; pseudogenized; gut flora; symbiont; reduced genome; åland; gotland;

   Abstract : Transposons are selfish, mobile genetic elements, moving within the genome. The transposase genemakes this possible, as it codes for the enzyme that catalyzes the movement. In the case of bacteria,they can also move horizontally between individual bacteria, and sometimes even between species. READ MORE
