Name: Date: Hour: GENETICS UNIT TEST 1. What molecule makes up the outside of a bacteriophage? What molecule is on the inside? Protein, nucleic acid/DNA 2. What type of organism do bacteriophages infect? bacteria 3. Describe the Hershey-Chase experiment. Why did they use radioactive sulfur and radioactive phosphorus? Phosphorus is found in DNA 4. What is the function of DNA? Store information 5. What happens when a portion of DNA is missing? Info is lost 6. What are the three parts of a DNA nucleotide? List the names of the bases too. Deoxyribonucleic acid, phosphate group, nitrogen base: adenine, thymine, guanine, cytosine 7. Who used X-ray diffraction? Franklin 8. What did Watson and Crick notice about the strands of DNA? They run in opposite directions 9. What is each new strand of DNA composed of? One old and one new strand 10. What are the rules for base pairing? A-T, G-C 11. What sugar is in RNA? ribose 12. What are the differences between DNA and RNA? RNA is single stranded, has ribose sugar, and uracil 13. What are the similarities between DNA and RNA? Phosphate groups, cytosine, and guanine 14. How can you tell when a strand of nucleic acid is RNA? It has uracil 15. How many types of RNA are there? What are their names?3: mRNA, tRNA, rRNA 16. Which types of RNA are involved in protein synthesis? all three 17. What is made during translation? What is made during transcription? Proteins, mRNA Name: Date: Hour: 18. How many nucleotides are in 1 amino acid? 2 amino acids? 3 amino acids? 3, 6, 9 19. What chance does a baby have of being a female? 50% 20. What percent of sperm carry an X chromosome? Y chromosome? 50% 50% 21. On what chromosome are sex linked genes found? X and Y 22. What is the genotype for a male? XY 23. On a pedigree, what does a square represent? Circle? Horizontal line? Vertical line? Male, female, marriage, children 24. What is nondisjunction? Failure of chromosomes to separate during meiosis 25. A baby has never been born without what type of chromosome? X 26. What is the result of nondisjucntion happening? Some gametes get extra copies of chromosomes and some have less 27. Why did Griffith call the process he studied transformation? Because harmless bacteria transformed to harmful bacteria 28. What is the correct sequence of the transfer of information in most organisms? DNA-RNA-protein 29. What are characteristics of polyploidy plants? Larger and stronger 30. How many copies of chromosome 21 does a person with Down Syndrome have? 3 31. List and describe the 4 chromosomal mutations. Deletion – some of the chromosome is deleted, inversion – some is reversed, duplication – some is doubled, translocation – piece breaks off and attaches to another one 32. What group of scientists did experiments with bacteriophages? Hershey and Chase 33. How did Hershey and Chase determine that it was DNA that infected a cell? Radioactive phosphorus is in it 34. What is mRNA made from? One complimentary strand of DNA 35. Fill in the table according to where you would see clumping if doing a blood typing test Name: Date: Blood type A B AB O Anti-A clumping clumping No clumping Hour: Anti-B clumping clumping No clumping 36. Which blood type is considered the universal donor – meaning they can give blood to anyone? AB+ 37. Which blood type is considered the universal recipient – meaning they can receive any type of blood? O- 38.
