Unit V: Protein and Gene Manipulation (40 Marks)

  • Chapter-1: Recombinant DNA Technology: Introduction, Tool of Recombinant DNA technology, making rDNA molecule, Introduction of recombinant DNA into host cells, Identification of recombinants, Polymerase Chain Reaction (PCR), DNA Sequencing.
  • Chapter-2: Protein Structure and Engineering: Introduction to the world of proteins, Structure-function Relationship in proteins, Characterization of proteins, Protein based products, Designing proteins (Protein Engineering).
  • Chapter-3: Genomics, Proteomics and Bioinformatics: Gene prediction and counting, Genome similarity, SNPs and Comparative genomics, Functional genomics, Proteomics, Information sources, Analysis using bioinformatics tools.

Note for Students: This unit covers the fundamental tools and techniques of genetic engineering along with the structural analysis of proteins and the complex study of genomes and proteomes.


Unit VI: Cell Culture and Genetic Manipulation (30 Marks)

  • Chapter-1: Microbial Cell Culture and its Applications: Introduction, Microbial nutrition and culture techniques, Measurement and kinetics of microbial growth, Isolation of microbial products, Strain isolation and improvement, Applications of microbial culture technology.
  • Chapter-2: Plant Cell Culture and Applications: Introduction, Cell and tissue culture techniques, Applications of cell and tissue culture, Transgenic plants with beneficial traits, Biosafety of transgenic plants.
  • Chapter-3: Animal Cell Culture and Applications: Introduction, Animal cell culture techniques, Applications of animal cell culture, Stem cell technology.

Note for Students: This unit delves into the methodologies of culturing microbial, plant, and animal cells, highlighting their diverse applications in technology and medicine.


PRACTICALS (30 Marks)

  • Use of special equipment in biotechnology experiments
  • Isolation of bacterial plasmid DNA
  • Detection of DNA by gel electrophoresis
  • Estimation of DNA by UV spectroscopy
  • Isolation of bacteria from curd & staining of bacteria
  • Cell viability assay using Evan’s blue dye exclusion method
  • Data retrieval and database search using internet site NCBI and download a DNA and protein sequence from internet, analyze it and comment on it
  • Reading of a DNA sequencing gel to arrive at the sequence
  • Project work

Note for Students: Students are required to perform these experiments to gain hands-on experience in molecular techniques, microbial analysis, and bioinformatics data retrieval.


Scheme of Evaluation: Practicals (30 Marks)

  • Two experiments: 6+6 marks (only one computer based practical)
  • Practical record: 04 Marks
  • Viva on Practical: 04 Marks
  • Project work: 10 Marks (Write up: 05 Marks; Viva on project: 05 Marks)

Note for Students: The evaluation process emphasizes hands-on proficiency in experiments, the quality of the project report, and the student's ability to defend their work during the viva.


Assessment Areas - Theory (70 Marks)

  • Demonstrate, Knowledge and Understanding (50%): State, name, list, identify, define, suggest, describe, outline, summarize, etc.
  • Application of Knowledge / Concepts (30%): Calculate, illustrate, show, adapt, explain, distinguish, etc.
  • Analyse, Evaluate and Create (20%): Interpret, analyse, compare, contrast, examine, evaluate, discuss, construct, etc.

Note for Students: The theory examination will include a variety of question types such as MCQs, Assertion-Reasoning, and Case-based questions, with an internal choice of approximately 33%.
