Keratin intermediate filaments are synthesized in the cytoplasm of cells. Disulfide bonds cannot be formed in the cytopl
The principle of quantitative reasoning explains that ratio, percentage and series logic determine correct calculation. Hence Keratin crosslinking happens in dead cells whose contents are oxidized 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.
