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

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
Four Differences DNARNA 1. Sugar Deoxyribose Ribose 2. Strand 2 stranded1 strand 3. Stored Nucleus Nucleolus 4. Bases ThymineUracil AdenineAdenine
Protein Synthesis Protein Sythesis-Translation Takes Place-- Ribosome Protein- long strand of amino acids Anticodon- three base sequence tRNA
EXTRA INFO Three parts of a nucleotide 1.Phosphate 2.Sugar----- Deoxyribose(DNA) or Ribose(RNA) 3.Nitrogen base
Where do the bases pair up on DNA? At the sugars
Protein Synthesis Using mRNA CODONS and tRNA Anticodons Remember to LOOK UP THE CODON on the chart not the ANTICODON
Ex GGG anticodon CCC CODON Amino Acid : PROLINE (CCC)
