| Question | Answer |
| Semi Conservative DNA Replication | Half original and Half new |
| The enzyme DNA helicase attaches and moves along the DNA molecule, unwinding the DNA and breaking hydrogen bonds between complementary bases. | The strands start to seperate. |
| Each strands act as a template. new individual DNA nucleotides are attracted to exposed complementary bases on template strand and base pairings occurs (A-T and C-G) | The enzyme DNA polymerase now joins the new nucleotides together through a condensation reaction forming phosphodiester bonds between the new nucleotides. |
| Semi conservative replication ensures that each new DNA molecule contains an original and a new strand and is identical to the original DNA. | Keywords semi conservative DNA helicase unwinds and unzips strands breaking hydrogen bonds template new nucleotides DNA polymerase |
