Presentation Transcript

  1. Wake-upWrite answers on back of old Wake-up • Explain the difference between prophase and telophase. • What is the end result of the cell cycle? • If a cell has 140 chromosomes and it undergoes mitosis, how many chromosomes will be present in the new cell?

  2. Protein Synthesis Christopherson

  3. Write down 3 “things” that you know about DNA

  4. What is a GENE? Instruction manual for our body Portion of DNA that “codes” (has directions) for a trait

  5. What is a TRAIT? A trait is a genetically determined characteristic

  6. Where is a Gene? • Within DNA • The nitrogen bases spell out the instructions.

  7. RNA Ribonucleic Acid Make up of Nucleotides Contains Phosphorus

  8. RNA Nucleotide A Phosphate Nitrogen Base C B Guanine Cytosine Ribose Adenine Uracil

  9. Types of RNA Messenger RNA Nickname: mRNA Made up of ONE strand of nucleotides

  10. mRNA Function Copy a message from a gene on DNA DNA mRNA

  11. Types of RNA Transfer RNA Nickname: tRNA Made up of ONE strand of nucleotides and a amino acid

  12. tRNA Function Carries amino acids to mRNA Amino Acids mRNA

  13. Types of RNA Ribosomal RNA Nickname: rRNA Made up of ONE strand of nucleotides mixed with the ribosome

  14. rRNA Function Forms peptide bonds between the amino acids rRNA Peptide Bond Amino acid Amino acid Amino acid Amino acid

  15. DNA versus RNA: # of Strands 2 strands 1 strand

  16. DNA versus RNA: Sugar Deoxyribose Ribose

  17. DNA versus RNA: Bonds with Adenine DNA RNA Adenine Thymine Adenine Uracil

  18. Review: Proteins Proteins are made up of amino acids that are held together by peptide bonds

  19. Brief summary of Protein synthesis(Video iTunes: 12:22-14:58) Make Proteins

  20. Brief Summary of Transcription Make mRNA from a gene on DNA
