  1. The DNA Connection

  2. Genes • Main function of genes are the production of proteins in an organisms cells • Proteins help determine the size, shape, color etc. of an organism

  3. Remember • Chromosomes are composed mostly of DNA • DNA is made of 4 nitrogen bases • Adenine • Thymine • Guanine • Cytosine

  4. Genes and DNA • A gene is a section of a DNA molecule that contains the information to code for one specific protein • A gene is made up of a series of nitrogen bases in a specific order • ATGACGTAC • Anywhere from several hundred to millions of these bases can form a single gene

  5. Order of the bases • Genes contain codes that determine the structure of proteins • The order of nitrogen bases along a gene forms a specific genetic code that specifies what type of protein will be produces

  6. Video • F:\BRC\Science 7\translation_basic.mp4

  7. Protein Synthesis Book • Make a book about the 4 steps of protein Synthesis • Use pg 100-101 for reference
