The circular pieces of dna are cut by
網頁Gel electrophoresis is a molecular biology method used to analyze and separate DNA fragments based on their size. When you use gel electrophoresis to help you with molecular cloning, you will also need to be able to interpret and analyze the results of your gel. For example, you may need to excise your digested plasmid DNA from agarose. 網頁Howôoôellôheóexïfánåggâeforeéncubation,€Ðdè ¯ ¯ ¨ãhick÷henèatched‡¸2ƒPolƒxliöalu„x1ƒñaæilepos=‡Q003070 „ „ „ „ „ „ †7 ...
