Course outcomes:

At the end of the course the student will be able to:

  • Understand the basics of protein structures, functional units, architectures and topologies
  • Understand the methods of isolation, purification and characterization of proteins
  • Apply the principles towards selective modification of proteins strictures and functions
  • Understand the Computational aspects of protein engineering and design, with specific case studies.

 

Question paper pattern:

The SEE question paper will be set for 100 marks and the marks scored will be proportionately reduced to 60.

  • The question paper will have ten full questions carrying equal marks.
  • Each full question is for 20 marks.
  • There will be two full questions (with a maximum of four sub questions) from each module.
  • Each full question will have sub question covering all the topics under a module.
  • The students will have to answer five full questions, selecting one full question from each module.
