An enzyme, according to Geoffrey M. Cooper, is a “catalysts that [can] increase the rate of virtually all the chemical reactions within cells. WebRestriction enzymes cut DNA strands at specific sequences to form ‘sticky ends’. The plasmid and the isolated gene are joined together by DNA ligase enzyme. If two pieces of DNA have matching sticky ends (because they have been cut by the same restriction enzyme ), DNA ligase will link them to form a single, unbroken molecule of DNA. Test ...
