Information to make a concept map about DNA and one about RNA.

1. DNA & RNA Parts and What-not

2. DNA What is it made of? What is it’s function? Other important scientists: Replication Who discovered the double helix shape? Which are made of: Define: Process: First model: Deoxyribonucleic acid Heredity Life processes Watson & Crick 1953 Copy nucleotides Phosphate group Deoxyribose (5-C sugar) Nitrogen base Adenine Thymine Cytosine Guanine Griffith ’28 & Avery ‘44 Hershey & Chase 1952 Chargoff 1949 Wilkins & Franklin 1952 Double helix AGTGCATGTTACCGA TCACGTACAATGGCT

3. RNA How does RNA differ from DNA? What forms does RNA take? How does it work? DNA – ATCCGTG RNA -- DNA – TACGAT RNA -- Ribose not deoxyribose Single helix Uracil not thymine Complements DNA UAGGCAC AUGCUA mRNA – messenger RNA Carries DNA “message” tRNA – transfer RNA Carries and delivers amino acids rRNA – Ribosomal RNA Ribosomes are made of it. Ribonucleic acid
