Frequently Asked Questions

Q: How are numerical problems in MBG-004’s TMA evaluated, and what units of measurement should I use for enzyme activity calculations?
A: Numerical questions assess unit conversions (e.g., mol/min/mg protein) and kinetic parameters (Km, Vmax). Always cite units explicitly (e.g., µM/s) and reference the course’s standard conditions, as deviations may incur partial deductions.

Q: Are there specific pass marks for MBG-004’s TMA, and how does IGNOU weight the qualitative vs. quantitative sections?
A: The TMA carries 30% weightage, with no fixed pass marks but a minimum of 50% required across all sections. Qualitative sections (e.g., short answers) are graded on conceptual accuracy, while numerical/descriptive parts demand precise calculations and adherence to syllabus-specific formulas.
