WebMeselson and Stahl used that fact to tell which kind of replication is correct by putting the DNA into liquid in test tubes as it reproduced, generation after generation. Step 1. grow bacteria (they used E.Coli) with only 15N present. Extract the DNA and put it in a test tube. WebDuring DNA replication, both the leading and trailing strands are created, however the leading strand is created continuously while the lagging strand is created intermittently in Okazaki fragments. These different methods of synthesis are a result of the antiparallel character of DNA and the requirement for exact and effective genetic material ...
