👉 Jukesena, also known as a Jukes-sequenometer, is a device used in molecular biology for measuring DNA sequence variation and mutation rates within cells. It works by using an enzyme called Juncalase to catalyze the removal of one strand of DNA from a cell's nucleus at the expense of another strand. This allows scientists to study and analyze DNA sequences that are not visible or accessible to other methods, such as fluorescence in situ hybridization (FISH) or PCR
