Microbiology and Genetics (Practical) [1]

Paper Code: 
25MBL128
Credits: 
04
Contact Hours: 
120
Objective: 

This laboratory course aims to develop practical skills in fundamental microbiological techniques, including aseptic handling, isolation, identification, enumeration, and preservation of microbes and mutants from various samples. Students will also analyze microbial metabolic capabilities, evaluate susceptibility to antibiotics and disinfectants, and apply Mendelian principles to study gene interactions.
