Presentation Transcript

  1. DNA Replication

  2. DNA Replication • Replication = DNA copies itself exactly • (Occurs within the nucleus) http://www.youtube.com/watch?v=zdDkiRw1PdU

  3. A. Facts of DNA Replication 1. Complementary base pairing rule: C - G A - T

  4. A. Basic Facts of DNA Replication 2. One side of DNA molecule is a template for making the other side (strand)

  5. B. Process of DNA Replication 1st -Uncoil & unzip DNA molecule Enzyme Helicase breaks the weak hydrogenbonds

  6. B. Process of DNA Replication Next the Enzyme Polymerase adds complementary Nitrogen-bases

  7. Replication Animation C - G A- T

  8. C. Semi-conservative replication • Each new DNA molecule contains one old strand & one new strand

  9. Lets Practice! -Original Strand: ACT GTT ACG GAC Complementary Strand: -Original Strand: TTT CAT TAC TTT Complementary Strand: -Original Strand: ACT GTT ACG GAC Complementary Strand: TGA CAA TGC CTG AAA GTA ATG AAA TGA CAA TGC CTG
