  1. Standard 8

  2. Which Statement describes a function of proteins in living organisms?A. They Serve as enzymes & catalysts B. They transmit genetic informationC. They are an energy storage molecule D. They serve as building Blocks for DNA

  3. Which function is characteristic of RNA, but NOT of DNA?A. transports proteins B. replicates itselfC. transports amino acidsD. carries genetic information

  4. A strand of DNA that contains the bases TACGAT replicates. Which base sequence is in the new strand produced during replication? • ATGCTA B. AUGCUA C. TACGAT D. CGTGGC

  5. As a result of base pairing in DNA, there is the same number of which two bases? • Guanine and Adenine • Adenine and Cytosine • Adenine and Guanine • Guanine and Cytosine

  6. Study the DNA nucleotide sequence .A C G C A G TWhich nucleotide sequence below represents the corresponding portion of an RNA strand?A. CTGCGTAB. GACAGCUC. TGCGTCUD. UGCGUCA

  7. Which sequence represents a DNA strand that would complement the following RNA strand ? CUA UGC AUG CCA • GAU ACG UAC GGU • CUA UGC AUG CCA • GAT ACG TAC GGT • CTA TGC ATG CCA

  8. The next two questions will use a chart

  9. Which student correctly identified possible percentages of nucleotide bases that could be present in a complete sample of DNA Student Amount of DNA Bases Hint: Which bases bind together?

  10. Student 3: • 15%, (T) 15%, (G) 35%, (C) 35% Adenine always binds to Thymine so the percentage has to be the same. This is also true for Guanine & cytosine.

  11. Which student correctly identified possible percentages of nucleotide bases that could be present in a complete sample of DNA

  12. What is the term that describes how substrates bind to an active site • Peanut Butter and Jelly • Lock and Key • Door and Doorway • Oil and Water

  13. DNA is made of what? • Nucleotides • Chromatin • Histones • Nucleolus

  14. RNA is mostly used for… • Producing DNA • Cellular Reproduction • Cellular Respiration • Producing Protein

  15. Protein does all of these things except… • Cellular repairs • Structuring the Human Body • Producing RNA • Functioning as an enzyme
