Briefly describe the 2-dimensional and 3-dimensional structure of tRNA . With diagram.
The antibacterial protein colicin E3 is an effective inhibitor of pro-
tein synthesis in prokaryotes. This protein is a nuclease, specifically
attacking a phosphodiester bond near the 3' end of the 16S RNA.
Suggest a mechanism for the effect of colicin E3 on translation.
