Biology is a fundamental discipline for understanding and applying life phenomena, and has shown tremendous progress over the past several centuries.
Moreover, in modern times, as academic boundaries are breaking down, the pace of development is becoming more astonishing as the technology from other basic science fields is being absorbed.
This rapid pace of development presents significant challenges in integrating all knowledge into a single textbook, and in many cases, the pace of new knowledge acquisition is not kept up, leaving theories as outdated theories.
However, if we look closely, we can see that the fundamentals of biology remain constant and serve as the backbone for the rest of the life sciences.

This textbook primarily covers essential knowledge that can be applied experimentally, in relation to topics covered in general biology courses at universities.
Beginning with the microscope, the most fundamental tool in the field of biology, it covers a wide range of topics, including basic explanations of many recently developed instruments, observation of animal and plant cells and microorganisms, genetic testing, observation and extraction of DNA structure, PCR, and dissection of experimental animals.
Additionally, at the end of each chapter, the objectives of the experiments performed in each chapter, the materials required for the experiments, the experimental protocol, and precautions and references for various risks that may arise during the experiments are attached, so that students who have not previously performed biology experiments can write experiment reports efficiently.
