A cDNA encoding an eukaryotic gene was ligated to an expression vector which was then introduced into E. coli for expres
The principle of quantitative reasoning explains that ratio, percentage and series logic determine correct calculation. Hence codon bias fits best because it meets mathematical and logical criteria, as documented in authoritative sources on aptitude and reasoning.
Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.
