As DNA replication is occurring, the molecule below is inserted into the nascent DNA strandas it lengthens. Which statement below is TRUE of the progress of replication immediatelyafterwards?Source: Wikipedia.A. DNA replication would halt because there is an extra 5′-phosphate group for DNA polymerase toadd the next nucleotide.B. DNA replication would halt because there is no 3′OH for DNA polymerase to add the nextnucleotide.C. DNA replication would halt because there is no 5′OH for DNA polymerase to add the nextnucleotide.D. DNA replication would continue, but the new strand would have to be built from 3′ to 5′.E. DNA replication would proceed normally

Solution

The statement is not provided in the question. However, I can tell you that DNA replication always proceeds in the 5' to 3' direction. This is because new nucleotides are added to the 3' end of the growing DNA strand, with the 3' OH group of the last nucleotide in the strand attacking the phosphate group of the incoming nucleotide. Therefore, if there is no 3' OH group available for the next nucleotide to be added, DNA replication would halt. So, the correct answer would be B. DNA replication would halt because there is no 3′OH for DNA polymerase to add the next nucleotide.
