Online protein making notes

  1. 1. DNA
  2. 2. ( DNA is a type of nucleic acid! ) Do you remember the four biomolecules? lipids, protein, carbohydrates and... nucleic acids!
  3. 3. <ul><li>The goal of the cell is to make </li></ul><ul><li>Proteins make your traits . </li></ul>proteins.
  4. 4. Proteins… <ul><li>Such as… </li></ul><ul><ul><li>hemoglobin : transport oxygen </li></ul></ul><ul><ul><li>insulin : hormone; removes sugar from blood </li></ul></ul><ul><ul><li>antibodies : fights infection </li></ul></ul><ul><ul><li>lactase : enzyme; digests milk sugar (lactose) </li></ul></ul><ul><ul><li>collagen : skin, bones, tendons </li></ul></ul><ul><ul><li>keratin : skin, hair, nails </li></ul></ul><ul><ul><li>myosin : muscle contraction </li></ul></ul>
  5. 5. DNA= Deoxyribonucleic Acid Location in cell: Nucleus
  6. 6. The nucleus contains chromosomes which contains DNA. DNA makes your genes.
  7. 10. Structure of DNA <ul><li>2 long strands of nucleotides in a spiral shape. </li></ul><ul><li>Ladder-shaped when “untwisted”. </li></ul>
  8. 11. <ul><li>The sides of the DNA “ladder” consist of alternating </li></ul><ul><li>(sugar) and </li></ul><ul><li>molecules. </li></ul>Deoxyribose Phosphate
