  5. Notes 10/14-10/15 • Note- taking worksheet with PowerPoint • Workbook p. 29-30

  6. DNA 10/15 • “twisted ladder” • Found in genes in chromosomes • Two sides of the ladder form the backbone of the DNA and support it • Each rung (or step) is made up of a pair of chemicals called bases – contain the genetic information • There are only 4 different bases – A, T, G, C • A always combines with T, and G always combines with C
