Presentation Transcript

  1. Mrs. Wharton’s Science Class DNA

  2. Deoxyribonucleic Acid • DNA- in chromosomes of the cell. Instructions for the cell. Genetic material. • Its in a shape of a DOUBLE HELIX- or twisted ladder

  3. Nucleotides • Consists of sugars, phosphates and nucleic acids • The order of nitrogen bases along a gene forms a genetic code that specifies what type of protein will be produced.

  4. Nitrogen bases for DNA • C- cytosine • G- Guanine • A- Adenine • T- Thymine

  5. RNA- Ribonucleic acid • Decides what proteins are built in all living things • RNA- single helix structure • RNA and DNA are held together by nucleic acids • Uracil instead of thymine • Same rules as DNA

  6. What do they do? • DNA holds on to instructions for cell ( head coach) • RNA sends directions to other cell parts ( Team leader)

  7. RNA vs DNA RNA • Uracil • Cytosine • Adenine • Guanine DNA • Thymine • Cytosine • Adenine • Guanine
