    1. Nucleic Acids: DNA & RNA Structure and Function

    2. DNA (Deoxyribose Nucleic Acid) • 2 strands twisted: _____________________ • Made of: _____________________ • Nucleotides made of: _____________________ _____________________ _____________________

    3. DNA (Deoxyribose Nucleic Acid) • DNA is genetic code for making: __________________________ • Genetic code is determined by sequence of: __________________________ • Nitrogen Bases pair up: __________________________

    4. DNA • DNA coiled up and condensed: _____________________________ • ______ Chromosomes in body cells of humans • ______ Chromosomes in sex cells (gametes) of humans • DNA and Chromosomes found in the: _____________________________ • Segment of DNA that codes for a protein: _____________________________

    5. Why do we need DNA and a Genetic Code? G  P  T __________  __________  __________

    6. Review • (A) What number is phosphate? • (B) What number is a nucleotide? • (C) What number is a sugar? • (D) What number is a nitrogen base? • (E) Is this DNA or RNA? • (F) What part of the cell is the molecule to the left found? • (G) A segment of this molecule that codes for a protein is called? • When this molecule is condensed and coiled up it is called?

    7. RNA (Ribonucleic Acid) • How many strands? __________ • Made from the genetic code of: __________ • Nitrogen Base Pairing: _________________

    8. RNA (Ribonucleic Acid) • Made in the: _______________________ • Travels out into the: _______________________ • Takes genetic code to the: _______________________ • RNA genetic code used at ribosome to put amino acids together into: _______________________

    9. Review Practice The Genetic Code:
