1 How DNA helps make you you

2 DNA Function Your development and survival depend on… Your development and survival depend on…  which proteins your cells produce,  how many are produced, and…  when they are produced. Random chance and your life experiences determine the rest Random chance and your life experiences determine the rest

3 Nucleic Acids Nucleotide (nucleic acid monomer) Nucleotide (nucleic acid monomer)  (Sugar)  Monosaccharide (Sugar) Ribose or Deoxyribose Ribose or Deoxyribose  Nitrogenous Base  Phosphate Group

4 Nucleic Acids RNA Single- stranded RiboseUracilDNA Double- stranded DeoxyriboseThymine Adenine Guanine Cytosine

8 DNA Function Review 1. What are the 3 parts of a nucleotide? 2. What are the 4 bases found in DNA? A. Which ones are complementary? B. Which base is found only in RNA? 3. Transcribe the following DNA strand: TACCTTGGATCGAAACCT 4. What sequence of amino acids would be produced from the RNA made in #3?
