1. DNA Abbreviation- Deoxyribonucleic Acid James Watson & Francis Crick- in 1953 discovered DNA was 2 strands and twisted Double Helix- 2 word term to describe DNA Codon---3 base sequence---ATA

2. Rules for base pairing for DNA Thymine to Adenine Adenine to Thymine Cytosine to Guanine Guanine to Cytosine

3. Complementary strand DNA to DNA A T G A T C G T G C A T A C T A G C A C G T

4. Parts Sugar ADENINE THYMINE CYTOSINE GUANINE PHOSPHATE

5. DNA Replication DNA Helicase- enzyme that unzips DNA for replication DNA Polymerase- enzyme that completes DNA replication Occurs- Synthesis or S stage of Interphase End Result- Sister Chromatids

9. RNA RNA- Ribonucleic Acid Codon---three base sequence of mRNA UGU Transcription- making of mRNA from DNA RNA polymerase- enzyme that unzips DNA for transcription. Ribose- the sugar in RNA

10. Base Pairing Rules for RNA to DNA  DNAmRNA  Thymine Adenine  Adenine URACIL  Cytosine Guanine  Guanine Cytosine

12. How mRNA and tRNA work together? 1.An mRNA codon pairs up with a tRNA anticodon. 2.tRNA anticodons bring with it an amino acid. 3.The amino acid it brings is based on the code in mRNA. 4.The mRNA and tRNA release from each other. 5.All that is left in the ribosome is a strand of AMINO ACIDS 6.ALSO KNOWN AS a PROTEIN

13. Four Differences DNARNA 1. Sugar Deoxyribose Ribose 2. Strand 2 stranded1 strand 3. Stored Nucleus Nucleolus 4. Bases ThymineUracil AdenineAdenine

14. Protein Synthesis Protein Sythesis-Translation Takes Place-- Ribosome Protein- long strand of amino acids Anticodon- three base sequence tRNA

15. EXTRA INFO Three parts of a nucleotide 1.Phosphate 2.Sugar----- Deoxyribose(DNA) or Ribose(RNA) 3.Nitrogen base

16. Where do the bases pair up on DNA? At the sugars

17. Protein Synthesis Using mRNA CODONS and tRNA Anticodons Remember to LOOK UP THE CODON on the chart not the ANTICODON

18. Ex GGG anticodon CCC CODON Amino Acid : PROLINE (CCC)
