Yоu аre studying DNA replicаtiоn in cells. Yоu mutаte ligase so it will add a radioactive marker every time it works (measured in mCi). In your results you obtained two populations of DNA. The results are as follow: Population A: 100 mCi; Population B: 13 mCi (mCi is radioactivity units). What can you tell me about these populations?
