Lesson 7 - Nucleic Acids  Learning Goals Use appropriate Use appropriate vocabulary vocabulary know know whatwhat nucleic nucleic acidsacids are are and and their significance their significance understand how form affects function understand how form affects function  Success Criteria IUse understand appropriate what the monomer and vocabulary polymers are for nucleic acids know what nucleic acids are and their Isignificance can continue to understand and apply bond understand theory how form affects function (dehydration/hydrolysis) I understand the purpose and function of nucleic acids  A. Overview Nucleic acids code for all proteins in living organisms DNA and RNA DNA codes for hereditary information RNA translates this code into proteins Proteins are the largest molecules in our body DNA RNA Protein!!!  B. Form DNA and is an anti-parallel, double helix RNA is a single helix or chain of molecules; it will sometimes fold in upon itself  i. Monomers Nucleotides are the monomers for DNA and RNA polymers Nucleotides are composed of: 1. Nitrogenous base (AGT or C) 2. Sugar (Ribose or Deoxyribose) 3. Phosphate functional group  Nitrogenous Bases Pyrimidines (thymine, cytosine, uracil) Purines (Adenine, guanine) ring shaped structures rich in nitrogen, hence the name  ii. Polymers DNA and RNA are polynucleotide chains Sugar-phosphate backbone of DNA is composed of phosphodiester bonds  C. Function DNA – Heredity RNA – Protein production  5`-phosphate (on the phosphate group) bonds to the 3` -carbon (of the sugar) of the next nucleotide in line  Adenosine Triphosphate ATP Ribose Sugar, Adenine, Three Phosphate groups  Removal of the last phosphate releases energy to be transferred around living organisms!
