Presentation Transcript

  1. DNA Structure & Replication Key Terms CSCOPE Unit 06 Lesson 01

  2. DNA • Deoxyribonucleic acid • Double-stranded nucleic acid (double helix shape—like a twisted ladder) • Contains genetic information for cell functions, growth, and division.

  3. Nucleotide • Basic building block of nucleic acids • Three parts: • Sugar • Phosphate group • Nitrogen base

  4. Deoxyribose Sugar • Sugar component in the backbone of DNA • 5-Carbon sugar

  5. Phosphate Group • Binds with sugar in DNA backbone • Phosphorous attached to four oxygen atoms

  6. Nitrogen Base Pairs • Nitrogen base pairs form the “rungs” of the DNA structure. • Adenine • Purine base that pairs with thymine • Thymine • Pyrimidine base that pairs with adenine • Cytosine • Pyrimidine base that pairs with guanine • Guanine • Purine base that pairs with cytosine

  7. Double Helix Nitrogenous Bases (A-T) and (C-G) Sugar Phosphate Backbone
