Presentation Transcript

  1. DNA & RNA Jackie Smith SOLs: BIO.6e-i

  2. The Discovery of DNA

  3. What is DNA? • Deoxyribo-nucleic Acid • Mechanism for heredity • Contained in all living cells (except some viruses) • Macromolecule

  4. What does DNA look like? • Double helix • Sugar backbone • Nucleotide base pairs • Anti-parallel arrangement

  5. DNA Base Pairs • Two types • Purines • Adenine and Guanine • Pyrimidines • Cytosine and Thymine • Hydrogen bonded to each other (A-T and C-G)

  6. Three Special types of DNA • Mitochondrial DNA • Chloroplast DNA • Bacterial DNA

  7. Double helix in a ring structure Free in cell Open Contains only genes Double helix in a string structure Enclosed in nucleus Protected Contains genes and “junk DNA” Prokaryotic v. Eukaryotic

  8. Review • DNA is a macromolecule. • It controls organism appearance and cellular function. • It is the mechanism for heredity • Base pairs correspond purine to pyrimidine.

  9. Next time! Genetics, Transcription, and Translation! How DNA and RNA work in the cell to create a product.
