- RECALL What is a chaperone?arrow_forwardREFLECT AND APPLY E. coli incorporates deoxyribonucleotides into DNA at a rate of 250 to 1000 bases per second. Using the higher value, translate this into typing speed in words per minute. (Assume five characters per word, using the typing analogy from Question 36.)arrow_forwardREFLECT AND APPLY A mutation that changes an alanine residue in a protein to an isoleucine leads to a loss of activity. Activity is regained when a further mutation at the same site changes the isoleucine to a glycine. Why?arrow_forward
- RECALL What is the ShineDalgarno sequence? What role does it play in protein synthesis?arrow_forwardREFLECT AND APPLY You are in the process of determining the amino acid sequence of a protein and must reconcile contradictory results. In one trial, you determine a sequence with glycine as the N-terminal amino acid and asparagine as the C-terminal amino acid. In another trial, your results indicate phenylalanine as the N-terminal amino acid and alanine as the C-terminal amino acid. How do you reconcile this apparent contradiction?arrow_forwardREFLECT AND APPLY Why is a trimming process important in converting precursors of tRNA and rRNA to the active forms?arrow_forward
