  1. DNA and Protein Synthesis Chapter 10

  2. 1. The monomer of DNA is Fatty acid Nucleotide Glucose Amino acid

  3. 2. The enzyme that unzips DNA in replication is RNA polymerase DNA polymerase Helicase Binding protein

  4. 3. The sides of DNA consist of Base and sugar Base and phosphate Phosphate and sugar Phosphate and amino

  5. 4. The purines are Adenine and guanine Cytosine and adenine Adenine and thymine Cytosine and guanine

  6. 5. The base pairings are A and G, C and T A and T, C and G A and C, G and T None of these are correct

  7. 6. DNA replication occurs when New cells are being formed Gametes are being formed A cell dies Both 1 and 2 are correct

  8. 7. Who was awarded with the discovery of the structure of DNA? Rosalind Franklin Francis Crick James Watson Gregor Mendel Both 2 and 3

  9. 8. Where does replication unzip? At the end of the DNA molecule being copied A Point on the DNA molecule in which the helicase is unzipping the DNA An Attachment of DNA polymerase to the old DNA strand None of these are correct

  10. 9. Mistakes in the DNA code are called Errors Mistakes Mutations mishaps

  11. 10. Where is DNA found in the cell? Cytoplasm Lysosome Vacuole nucleus

  12. 11. RNA differs from DNA in that it Single stranded and not double stranded Contains ribose and not deoxyribose Contains thymine and not uracil 1 and 2 are correct All are correct

  13. 12. The function of Messenger RNA is to Bring an amino acid to the ribosome Make up the ribosome structure Copy the DNA code and bring it to the ribosome Copy the DNA code and bring it to the mitochondria

  14. 13. tRNA is shaped like a Square Circle Oval cloverleaf

  15. 14. Protein synthesis takes place at the Nucleus vacuole Mitochondria Ribosome

  16. 15. Genes in your DNA make Carbohydrates Lipids Nucleic Acids Protein Both 1 and 2 Both 3 and 4

  17. 16. tRNA molecules carry_____ to the ______ DNA, nucleus DNA, ribosome Amino acids, ribosome Amino acids, nucleus

  18. 17. How many bases must a gene contain to code for a protein with 500 amino acids? 250 499 1000 1500

  19. 18. The process of mRNA making a copy of DNA is called Replication Transcription Translation None of these

  20. 19. A purine will always match with a purine True False

  21. 20. If the DNA code is ACGTTTACG, what is mRNA AGCAAATGC TCGTTTACG UGCAAAUGC UGCAAATGC

  22. 21. The types of bonds that form between the sides of the ladder are Covalent Hydrogen Ionic Polar covalent

  23. 22.The start codon is Threonine Valine Methionine serine

  24. 23. Each strand of mRNA codes for 1 amino acid True False
