Anatomy

Anatomy is the branch of biological science concerned with the study of the structure and organization of living organisms, particularly the human body.

Bacterial Genetics

Bacterial genetics is the field of study that focuses on the mechanisms of heredity and variation in bacteria, particularly how genetic information is transmitted, modified, and expressed in prokaryotic organisms.

Basic Microbiology

Biochemistry

Biochemistry is the branch of science that explores the chemical processes and substances occurring within living organisms, bridging biology and chemistry to understand life at the molecular level.

Cell Biology

Cell biology, also known as cytology, is the branch of biology that studies the structure, function, and behavior of cells. Cells are the fundamental units of life, and understanding them provides insights into how organisms grow, reproduce, and carry out essential processes.

Genetics

Genetics is the branch of biology that deals with the study of genes, genetic variation, and heredity in living organisms.
