This lab manual introduces students to core techniques in molecular and cellular biology through hands-on experiments involving cell structure, molecular cloning, and protein expression and analysis. Students investigate eukaryotic cell organization, isolate and manipulate bacterial DNA, perform bacterial transformation, analyze plasmids, and examine protein expression using techniques such as SDS-PAGE and Western blotting. The manual also includes foundational laboratory skills, including micropipetting, spectrophotometry, and experimental materials preparation.
