_______________________________________ Chapter 6 Section 2 Review 10. A long string of amino acids forms a(n) ______________________. 11. Instructions for making a protein are given by Section: How DNA Works 1. How much DNA does a single cell in your body hold? each _________________ 12. List two examples of things proteins help determine about you. ____________________________________________________________________ _______________________________________________ UNRAVELING DNA _______________________________________________ _____ 2. What shape does DNA take in a cell that lacks a nucleus? a. a loose loop c. a tight chain b. a structure d. a protein 13. Several forms of RNA or ______________________ help change DNA code into proteins. _____ 3. What are the structures that strands of DNA are bundled into in a cell with a nucleus called? a. nucleotides c. chromosomes b. loose loops d. tight chains 4. A string of nucleotides that give the cell information about a certain trait is known as a(n) ______________________. 5. How many chromosomes does a human cell have before division? 14. Because it is so similar to ______________________, RNA can serve as a temporary copy of a DNA sequence. 15. The “factory” that assembles proteins is known as a(n) ______________________. 16. A mirror-like copy of DNA called ______________________ moves from the nucleus to the ribosome. ____________________________________________________________________ 6. When a cell is ready to divide, how many chromatids make up a chromosome? 17. Another form of RNA called ______________________ matches amino acids ____________________________________________________________________ with the bases on the messenger RNA. GENES AND PROTEINS 7. The ______________________ code is read like a book. 8. The alphabet of the code is made of the ______________________. 9. Groups of three bases are the codes for specific ______________________. _______________________________________ Put the following steps in making a protein in order by putting a number in the space provided: 1 for step 1, 2 for step 2, etc. _____ 18. The RNA copy is fed through the ribosome. _____ 19. Transfer RNA molecules deliver amino acids to the ribosome. _____ 20. Transfer RNA molecules pick up amino acids from the cytoplasm.
