- Please ASAP. Thanku The process by which base pairs combine with each other to form a strand of DNA is called _______. denaturation annealing initial incubation extension mitosisQuestion 1 DNA replication is said to be semi-conservative because Question 1 options: each daughter duplex contains one strand from the original DNA duplex and one newly synthesized DNA strand each of the original DNA strands is used as a template by a DNA polymerase to make a complementary DNA strand Replication is not conserved between daughter cells DNA polymerase adds dNMP residues to the free 3′ hydroxyl group of the growing DNA strand Question 3 DNA synthesis is said to be semi-discontinuous because: Question 3 options: Only the Lagging strand is synthesized continuously Only the Leading strand is synthesized continuously Both leading and lagging strands are synthesized discontinuously Replication starts ar replication fork Question 4 Unlike RNA polymerases, DNA polymerases cannot…Can somone check my answers are in bold please for both questions :Which is NOT true of the different conformations of DNA?
