PPT-THE MECHANISM OF DNA REPLICATION

By Dr R C Nath Associate Professor Department of Zoology Govt Degree College DMR Structure of a DNA molecule It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material. GO TO . BIOINTERACTIVE WEBSITE. DNA replication questions. Why is DNA replication so important?. In what part of the cell cycle does DNA replication occur?. What enzyme brings in the new DNA nucleotides that form complimentary pairs with the old DNA strand?. 20.1 part 2. DNA replication. Earlier on in this unit we learned about mitosis or cell division.. In order for mitosis to occur and chromosomes to duplicate themselves, the DNA must copy itself exactly.. The function of DNA in the cells is to. preserve genetic information.. transfer genetic information to new cells as the strands of DNA are copied.. DNA Replication. In . DNA replication. ,. the strands in the original or parent DNA molecule separate to allow the synthesis of complementary DNA strands.. Semiconservative vs. Conservative. DNA Polymerase. RNA Primase.
