Answer :
It is given in the question that the E. coli chromosome contains 4,639,221 base pairs.
As we know that the one turn of double-stranded chromosome contains ten base pairs.
Therefore, if we need to find the number of turns for 4,639,221 base pairs, then we need to divide it by ten.
Hence, the number of turns of the double helix that is required for unwinding during replication of E. coli is 463922.
