Presentation Transcript

  1. Bell Ringer: What is mutation? How does this impact cell division, DNA replication, mitosis and meiosis?

  2. DNA: The Blueprint of Life

  3. Replication

  4. Phosphate Sugar (Deoxyribose) Nitrogenous Base 1 3 2 A C A G C G G A C A G C T T T C C T G G

  5. Question 1. What is the sequence of each strand of DNA? Question 2. What is the complimentary sequence? Top Sequence: GACGATTGACComplimentary: CTGCTAACTG Bottom Sequence: CTGCTAACTGComplimentary: GACGATTGAC

  6. Replication: Process by which a cell makes a copy of the DNA in its nucleus http://www.youtube.com/watch?v=hfZ8o9D1tus

  7. Transcription

  8. mRNA (messenger RNA): RNA that copies the coded message from DNA in the nucleus and carries the message into the cytoplasm. Phosphate Sugar (Ribose) Nitrogenous Base 1 3 2 Question 3. Is mRNA single-stranded or double-stranded? Question 4. What are 3 differences between DNA and RNA?

  9. Question 5. What is the mRNA sequence? GACGAUUGA Question 6. What is the sequence of the template DNA? CTGCTAACT Why does sequence matter?

  10. Genetic Code:Order of nitrogenous bases that specifies what type of protein will be produced. Gene: Segment of DNA that codes for a protein Genetic Code ACT C T A C T G Gene

  11. Transcription: Process by which information on a strand of DNA is copied into a strand of mRNA. http://www.dnatube.com/video/3450/DNA-Transcription

  12. Translation

  13. Genetic Code ACT C T A C T G Question 7. What would the mRNA sequence be? GAC GAU UGA GAC GAU UGA Codon: Sequence of three nucleotides that encodes a specific amino acid.

  14. Protein Synthesis Question 8. Where does replication take place? Question 9. Where does transcription take place? Question 10. Where does protein synthesis take place?

  15. mRNA attaches to the ribosome, where protein synthesis begins. Transfer RNA: RNA in the cytoplasm that carries an amino acid to the ribosome and adds it to the growing protein chain.

  16. Attached amino acids become a protein chain. Question 11. How many bases make a codon? mRNA read in ‘triplicate’- 3-letter codes of bases specific for an amino acid

  17. Convert DNA sequence to mRNA. Use the chart to match codons to amino acids. GAC GAU UGA 2. Val Val STOP ACT C T A C T G

  18. Translation: The process by which a protein is synthesized from the information encoded on an mRNA strand. http://go.distance.ncsu.edu/animations/proteinsynthesis/
