Unformatted text preview: 7. How can a protein be reversibly modified to change its conformation and/or activity? How does this relate to the DNA binding proteins discussed in lecture 11? What is meant by allosteric inhibition? What is meant by competitive inhibition? 8. What is meant by “feedback regulation”? How is cruise control in a car an example of feedback regulation? What is a biological example of feedback regulation? 9. Are regulatory proteins encoded by genes? Why would you expect a sensory/regulatory protein to always be present, even if it is at a relatively low level of abundance? 10. Say that the maximum amount of transcription that is possible from a single promoter is 100 transcript initiations per minute. Design a promoter and regulatory region that could vary from 1 to 100 transcripts per minute using just negative regulation. Design a promoter and regulatory region that could vary from 1 to 100 transcripts per minute using just positive regulation....
