Which statement correctly describes why the dna synthesis is discontinuous on one template strand while continuous on the other? (select all that apply.) a. it is due to the semiconservative nature of dna replication. b. it is due to the nature of the dna polymerase which can only add new nucleotide at the 3' end. c. it is due to difficulty in unwinding the dna template for replication. d. it is due to antiparallel nature of the dna molecule. e. it is due to the fact that the dna polymerase is not active enough.
