  5. C

  6. #3 Glutamic acid is the amino acid that should Be coded on hemoglobin, but for Sickle-cell Anemia this amino acid is coded for Leucine Valine A: B: Glycine Tyrosine C: D:

  7. B

  8. #4 Crossing over occurs in Interphase I Interphase II A: B: Prophase I Prophase II C: D:

  9. C

  10. #5 One difference between meiosis and mitosis is Mitosis forms 2 haploid cells Meiosis forms 4 diploid cells A: B: Meiosis produces genetically different cells Mitosis produces genetically different cells C: D:

  11. D

  12. #6 Chromosomes can be distinguished on Karyograms by what 2 features? Length and width Banding patterns and length A: B: Homologous pairs The centromere and homologous pair C: D:

  13. B

  14. #7 If 2 heterozgyous parents had offspring What are the possible genotypes? 50% homozygous recessive 50% Heterozygous A: B: 100% Homozygous 100% Heterozygous C: D:

  15. B

  16. #8 Polymerase chain reaction (PCR) is useful for forensics because It gives you the DNA profile It separates the base pairs A: B: Makes millions of copies of the DNA Uses ligase to cut the DNA C: D:

  17. C

  18. #9 Gel electrophoresis separates DNA by Size and charge Size of the DNA fragments A: B: Charge of the DNA The amount of DNA C: D:

  19. A

  20. #10 Genetic engineering involves Transfer of DNA Transfer of Chromosomes A: B: Transfer of Genes Transfer of the nucleus C: D:

  21. C

  22. #11 Gene transfer is possible because The genetic code is universal Most amino acids are transferred A: B: Factor IX allows for the transfer mRNA can transfer C: D:

  23. A
