Presentation Transcript

  1. Protein Synthesis

  2. Write the complementary DNA strand for each of these DNA strands: DNA • DNA • GAATTACA • CCAATTAG • ATAGACAG • CCAGTACA

  3. Here is a practice website if you are connected to the internet: http://www.pbs.org/wgbh/aso/tryit/dna/shockwave.html

  4. Each of the 96 columns represents one DNA sequence. A different colored dye attached to each of the four nucleotides.

  5. Replication

  6. Semi-Conservative Replication Each strand of the original molecule acts as a template for the synthesis of a new complementary DNA molecule

  7. With semi-conservative replication, each new strand is ½ new and ½ old

  8. Examples of DNA Replication

  9. RNA(ribo-nucleic acid)

  10. Differences between DNA and RNA • Different sugars (DNA=deoxyribose) (RNA=ribose) • RNA is single stranded (1 side) DNA is double stranded (2sides) • RNA has “U” (uracil) DNA has “T” (thymine)

  11. Always remember… RNAlovesU

  12. Write the RNA strand for each of these DNA strands: • RNA • ½ Strand of DNA • GAATTACA • CCAATTAG • ATAGACAG • CCAGTACA

  13. Transcription The process by which DNA is copied into mRNA

  14. mRNA Messenger RNA, is the copy of the DNA that goes from the nucleus to the ribosome

  15. FACTProteins are made up of amino acids

  16. tRNA Transfer RNA, matches up with mRNA and has an amino acid on its top

  17. CODON Each combination of 3 nucleotides on a strand of mRNA

  18. ANTICODON Each combination of 3 nucleotides on a tRNA

  19. Translation The decoding of a mRNA message into proteins

  20. rRNA Ribosomal RNA, glues together all of the amino acids into a polypeptide chain
