The shape of a DNA molecule is called a _______________________, which looks like a ________________ __________________. Page 293 2. What is a gene? 3. What is DNA? Page 294-295 4. What Scientists discovered that DNA is the hereditary material in the cell? Page 296-297 5. What Scientists discovered the shape and structure of DNA? 6. DNA is made of subunit linked together called _______________________________. 7. What are the three parts of a nucleotide? 8. What are the four nitrogen bases in DNA? 9. The base-pairing rule states that adenine always pairs with ___________________, and guanine always pairs with _____________________. 10. These nitrogen bases are bonded together with what kind of bond? Page 298-299 11. Remember the T base always pair with the A base and the C base always pairs with the G. If one side of DNA reads TTAACCGG what will the complimentary side read? Page 300-301 12. What is DNA replication? 13. What are the three steps of DNA replication? 14. What are the proteins called that unwind the DNA? 15. What does DNA polymerase do? Page 302-303 16. What kind of molecule performs most of the functions of a cell? 17. What does RNA do? 18. What is meant by gene expression? Page 304-305 19. The process of making RNA from DNA is called what? 20. Using the information in RNA to make a protein is called what? 21. Explain the three things that makes RNA different from DNA. 22. What are the three types of RNA? Page 306-307 23. Where does transcription take place and how many steps are needed to do transcription? 24. Where does translation take place? 25. A codon is like a word to the genetic code. How many letters are in this word or Codon? 26. The codon is code word for a specific amino acid used to make a certain protein. How many amino acids are used to make proteins? 27. Can you break the code? What amino acids should be used for the following codons (code word)? CCG ____________________ ACG ____________________ Page 308-309 There are 5 steps in translation. Briefly describe what happens in each step. 28. Step 1 29. Step 2 30. Step 3 31. Step 4 32. Step 5
