Name: ______________________ Class: _________________ Date: _________ ID: A 11.5 Questions Modified True/False Indicate whether the statement is true or false. If false, change the identified word or phrase to make the statement true. ____ 1. During DNA replication, only one strand of DNA serves as a template. _________________________ ____ 2. The anticodon AGA is complementary to the codon TCT. _________________________ ____ 3. The key enzyme involved in transcription is RNA polymerase. _________________________ Completion Complete each statement. 4. The triplet of bases on the end of a tRNA molecule is called a(an) _________________________. 5. The process of joining exons together to form an mRNA molecule is called _________________________. 6. During transcription, the _________________________ between base pairs are broken. 7. A mutation will cause the cell to make an incomplete polypeptide if the mutation results in a(an) _________________________. 8. The _________________________ portion of a tRNA molecule determines the type of amino acid that bonds with the tRNA. Short Answer 9. What causes translation to stop? . 10. What must happen to a DNA molecule before RNA polymerase can make RNA? 1 Name: ______________________ ID: A Other USING SCIENCE SKILLS Figure 11-1 11.
