Yоu isоlаted оne lineаr аnd one circular double-stranded DNA molecule in the lab. Subsequent analysis showed that each one contains 3 EcoRI recognition sequences. How many DNA fragments will there be following complete digestion with EcoRI? The linear molecule will generate [blank1] fragments, and the circular one will generate [blank2] fragments.
