  1. DNA Replication

  2. DNA Replication • Replication = DNA copies itself exactly • (Occurs within the nucleus) • Any mistake in copying = mutation • DNA mutation = chromosomal mutation

  3. A. Basic Facts of DNA Replication 1. Complementary base pairing makes replication possible 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) ?’s 1-3

  5. B. Process of DNA Replication • Uncoil & unzip DNA molecule • Enzyme (-ase) breaks weakHydrogen Bond between bases

  6. B. Process of DNA Replication 2. Enzyme brings in complementary N-bases DNA Replicase

  7. B. Process of DNA Replication 3. Insert N-bases DNA Replication Tutorial (Go here for on-your-own learning/review) trc.ucdavis.edu/.../week5/06dnareplication.html

  8. Replication Moovie C - G A- T

  9. C. Semi-conservative replication • Each new DNA molecule contains one old strand & one new strand ?’s 4-6

  10. DNA vs. RNA

  11. DNA vs. RNA

  12. DNA vs. RNA ?’s 7-12
