When mitotic chromosomes are subjected to proteolytic enzyme (trypsin) treatment followed by staining with the chemical dye Giemsa, they generate distinct chromosome-specific patterns called G-bands.

#Unit 2. Cellular Organization

Attenuator riboswitch (Leader sequence) region 1 is translated  till UGA (R1-2) at high trp concentration due to two conditions

 Ribosome quickly crosses codon 10, 11

After crossing codon 10, 11 ribosome prematurely terminated at UGA at the end of Region 1

The central bond in this case is the peptide bond, where rotation is constrained. The peptide bond is normally (99.6% of the time) in the trans configuration, constraining  to a value of w=+_180. For a rare cis peptide bond, w=0.
