Biochemistry MCQs | Part-1

Biochemistry is the study of chemical processes in living organisms. It combines biology with chemistry, physics, mathematics, microbiology, and genetics to understand how life works at the molecular level.

Here we design a quiz test containing 50 MCQs on biochemistry. It will help you to prepare for competitive exams or interviews.
