DNA, RNA, & PROTEINS REVIEW (We did this one in class) 1. Making a copy of DNA is called _________________________. 2. Which nitrogen base isn’t used during this process? 3. Name the enzyme you learned about that adds the complementary nucleotides and spell checks to make sure the new copy is correct. http://bio.usuhs.mil/biochem4.html 6. This process of making copying an RNA message from the DNA code is called ____________________. 7. Tell where in the cell this happens.

USE THE mRNA CODE WHEEL to tell the amino acid sequence coded for by the following message: U C A A A A U U C Image from: Biology; Miller and Levine; Pearson Education publishing as Prentice Hall; 2006 9. Which kind of RNA has an ANTICODON region and carries the amino acids to the ribosome? 10. B = ? 11. F = ? 12. C = ? Image from: Biology; Miller and Levine; Pearson Education publishing as Prentice Hall; 2006 13. Tell one way DNA is different from RNA. 17. When making DNA, CYTOSINE always pairs with _______________________. 18. Using an RNA message to make a protein is called _______________________. 19. Name this subunit used to build DNA and RNA. Image by Riedell 20. Name the spot where RNA polymerase attaches to the DNA during TRANSCRIPTION. 21. Give the complementary DNA strand. A T T G C C A G C 22. NAME THIS KIND OF RNA. 23. Name the molecule attached at the arrow. Image modified from: Biology; Miller and Levine; Pearson Education publishing as Prentice Hall; 2006 25. PROTEIN SYNTHESIS could also be called ___________________. 26. Nitrogen bases made up of TWO RINGS are called ________________ 30. Name this kind of mutation.

Image from: Biology; Miller and Levine; Pearson Education publishing as Prentice Hall; 2006 34. Name the nucleic acid that is double stranded and contains deoxyribose sugar. 35. Name the woman whose X-ray images of DNA helped James Watson and Francis Crick to figure out the structure of DNA. http://www.time.com/time/time100/scientist/profile/watsoncrick.html http://en.wikipedia.org/wiki/Rosalind_Franklin 36. Name the enzyme involved with TRANSCRIPTION. CHECK ANSWERS ANSWERS 1.replication 2. uracil 3. DNA polymerase 6. transcription 7. in nucleus 8. serine-lysine-leucine 9. tRNA 10. mRNA 11. codon 12. ribosome 13. DNA Double stranded contains deoxyribose sugar A,T,G,C No uracil Carries genetic information Stays in nucleus RNA Single stranded contains ribose sugar A,U,G,C No thymine Carries info from DNA to cytoplasm; helps with protein synthesis Made in nucleus; works in cytoplasm 17. guanine 18. transcription 19. nucleotide 20. promoter 21. T A A C G G T C G 22. tRNA 23. amino acid 24. D- DNA carries the genetic code 25. translation 30. inversion 31. False; mutations that increase survival and reproduction can be helpful 32. Amino acid 33. anti-codon 34. DNA 35. Rosalind Franklin 36. RNA polymerase
