Honors Biology Chapter 10 Guided Reading Assignment Name _________________________ 1. What is molecular biology? 2. Review: What are monomers and polymers? How are they related? 3. Draw the detailed structure of a DNA nucleotide. 4. What makes up the “backbone” of DNA? 5. How is an RNA nucleotide different from a DNA nucleotide? 6. What are the four bases for DNA? For RNA? 7. What is the complementary sequence to GGCTAATTGCCCGTA? 8. What is DNA replication? 9. How does complementary base pairing make possible the replication of DNA? 10. Why is the model for DNA replication said to be “semiconservative?” 11. What is an origin of replication? What does it have to do with a replication fork? 12. What does it mean to say that DNA is anti-parallel? 13. What is the function of the enzymes: DNA polymerase & DNA ligase? Page 1 of 2 14. Define the following terms: a. Transcription b. Translation c. Triplet code d. Codon e. Genetic code 15. What are the functions of transcription and translation? 16. What molecule acts as a bridge between DNA and proteins? 17. Label the diagram 18. A particular protein is 250 amino acids long. In the gene for this protein, how many nucleotides are necessary to code for this protein? 19. Translate the mRNA sequence GGUAAAUGC? 20. Label the diagram below using the following word bank: RNA polymerase, RNA nucleotides, Template strand of DNA, Newly made RNA: 21.
