Presentation Transcript

  1. DNA, RNA, and DNA Replication

  2. DNA vs RNA • Deoxyribonucleic Acid • Double Helix Shaped • Forms: Nuclear Mitochondrial Chromosomal • Never leaves Nucleus • Contains C,G, A, T • Ribonucleic Acid • Single Helix Shaped • Forms: Messenger Transfer Ribosomal • Leaves Nucleus • Contains C, G, A, U

  3. DNA Base Pairing • Adenine bonds with Thymine • Cytosine bonds with Guanine • A-T or T-A • C-G or G-C

  4. RNA Base Pairing • Adenine bonds with Uracil • Cytosine bonds with Guanine • A-U or U-A • C-G or G-C

  5. DNA Structure • Phosphate Group (PO4) • Deoxyribose Sugar • Nitrogen Base Pair • Deoxyribose Sugar • Phosphate Group (PO4)

  6. DNA Structure Mobile • Color each part. • Cut out the individual pieces. • Glue or paste together. • Attach string for individual mobiles. • Tape all of the classses together and make a huge strand to hang from ceiling. • Attach to cardboard and make a puzzle.

  7. DNA Replication

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

  9. Basic Facts of DNA Replication 1. Complementary base pairing makes replication possible C - G A - T

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

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

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

  13. 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

  14. Replication Movie C - G A- T

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

  16. DNA vs. RNA

  17. DNA vs. RNA

  18. RNA vs. DNA

  19. QUESTIONS TO KNOW • What is the shape of DNA?

  20. QUESTIONS TO KNOW • A Double Helix

  21. QUESTIONS TO KNOW • Where is DNA found within the cell?

  22. QUESTIONS TO KNOW • In the nucleus only.

  23. QUESTIONS TO KNOW • What is the result of a mistake in the copying portion of DNA replication called?

  24. QUESTIONS TO KNOW • A mutation

  25. QUESTIONS TO KNOW • Cytosine bonds with?

  26. QUESTIONS TO KNOW • Guanine

  27. QUESTIONS TO KNOW • Adenine bonds with what in DNA? RNA?

  28. QUESTIONS TO KNOW • Thymine • Uracil

  29. QUESTIONS TO KNOW • What is the opposite DNA base pair of: C-T-A-G-G-C-T-T-A-A-C-G-G-T-T-A-C

  30. QUESTIONS TO KNOW • C-T-A-G-G-C-T-T-A-A-C-G-G-T-T-A-C G-A-T-C-C-G-A-A-T-T-G-C-C-A-A-T-G

  31. QUESTIONS TO KNOW • Which base pair is that of RNA? 1. C-T-A-G-G-C-T-T-A-A-C-G-G-T-T-A-C 2. C-A-U-G-G-C-A-A-U-U-G-C-C-U-U-G 3. G-T-U-C-C-G-T-U-T-U-C-G-G-T-A-C

  32. QUESTIONS TO KNOW 1. C-T-A-G-G-C-T-T-A-A-C-G-G-T-T-A-C 2. C-A-U-G-G-C-A-A-U-U-G-C-C-U-U-G 3. G-T-U-C-C-G-T-U-T-U-C-G-G-T-A-C
