Biosystematics, taxonomy and evolution

• Composition and assessment of the taxonomic diversity/biodiversity in a habitat (e.g. grassland, arid land, wet land etc.)
• Estimation of gene and genotypic frequencies in light of Hardy-Weinberg law based on facial traits/thumb prints, ABO blood group data etc.
• Project: Preparation of models showing the status of certain taxa or species in a particular habitat.

Cell Biology

• Preparation of different cell types: Liver Hepatocytes , Adipocytes, Spleen cells
• Study of Polytene chromosomes in salivary glands of Chironomus larva/Drosophila
• Light microscopic examination and preparation of tissue sections.
• Study of mitotic and meiotic chromosomes from permanent prepared slides.
• Preparation of slides for mitotic study.
• Preparation of slides for meiotic study in the testis of grasshopper.
• Preparation of multipolar nerve cell from the spinal cord of a mammal.
• Barr body preparation in buccal epithelial cells.

Biochemistry

• Qualitative analysis of Lipid, protein and Carbohydrate samples
• Colorimetric/Spectrophotometric estimation of :

1. Carbohydrate-Glucose,glycogen,cholesterol etc.
2. Protein
3. Phospholipids
4. Nucleic acids: DNA,RNA

• Analysis of enzyme activity
• Study of temperature effect on enzyme action
