It is observed that in a multiple sequence alignment of homologous proteins, there is an absolutely conserved Glycine re
In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore No other amino acid can occupy this position in the Ramachandran map and henc... is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.
