Using the schematic below of the 5 ' region of the Trp operon in E . coli, answer the following: a) If charged Trp-tRNAs are in low abundance in the cell, which region(s) bind(s) together? ( 2 pt ) b) Is the Trp operon transcribed? (2 pt) Problem 3 (4 pts) 1) Could transcription attenuation be used to regulate genes in eukaryotes? Explain why or why not. 3) Why would a eukaryotic cell be unable to translate the permease gene on a polycistronic LacZYA mRNA injected into the cytoplasm? .
