Presentation Transcript

  1. Genetics Nucleic Acids and Protein Synthesis Cell Growth and Division Heredity Genetic Engineering

  2. Nucleic Acids and Protein Synthesis

  3. DNA • Nucleic acid that stores and transmits the genetic information from one generation of an organism to the next.

  4. Nucleic Acid: large, complex organic molecule that stores genetic information in nucleotides C

  5. Nucleotides • 5 Carbon sugar, deoxyribose • Phosphate group • Nitrogenous base

  6. 4 Nitrogenous bases • 2 Purines • Adenine • Guanine • 2 Pyrimidines • Thymine • Cytosine

  7. Replication Hello Dolly! • DNA molecule is unzipped • 2 separate strands are available

  8. The separated strands serve as a mold, for a new strand • Complementary nucleotides attach to the mold

  9. Adenine and Thymine are complimentary • Guanine and Cytosine are complimentary

  10. RNA • Sugar: ribose • Single stranded • Uracil in place of Thymine

  11. Transcription • The DNA code is first transferred into mRNA • mRNA is the first copy made of the mold

  12. mRNA carries the information out of the nucleus and into the cytoplasm.

  13. Translation • mRNA attaches to the ribosomes • tRNA collect amino acids and carry them to the mRNA

  14. The anticodons of tRNA attach to the appropriate codons of mRNA. • The amino acids are forming new specific proteins

  15. The new proteins are now organized to provide new strands of DNA • EXACT COPIES!
