History of DNA1.To understand how bacteria caused pneumonia.2.S has a capsule (virulent), R lacks it (non-virulent).3.R + dead S: mice died, living S found.4.A "transforming factor" made R turn into S.5.DNA6.R became deadly by picking up capsule gene from S.7.DNA, RNA, proteins.8.Transformation still occurred.9.Transformation still occurred.10.Transformation didn’t occur.11. DNA is the transforming factor.12.Adding DNA to bacteria.13.Adding DNA to eukaryotic cells.14.Transfection is for eukaryotes, transformation for bacteria.15.Transgenic organism16.Crops, medicine, researchDNA Structure and Replication1.Strands run in opposite directions.2.Nucleotide.3.Phosphate, sugar, base.4.Covalent bonds; strands held by hydrogen bonds.5.A-T, G-C.6.One old, one new strand per DNA molecule.7.Adds bases, proofreads.8.A-T, G-C.9.RNA primer gives DNA Polymerase a starting point (free 3' end).10. Complementary strands:●Strand 1: 5’ - ACTGGCAACTTGCA - 3’New strand: 3’ - TGACCGTTGAACGT - 5’●Strand 2: 3’ - TGACCGTTGAACGT - 5’New strand: 5’ - ACTGGCAACTTGCA - 3’
