Summary Introduction
Introduction:
Ever organisms present in the environment contains cell. The cell is the basic “fundamental unit” of life. The cell contains three major regions. These are “plasma membrane, cytoplasm, and nucleus.” The nucleus contains chromosomes. Chromosomes are “thread-like” in appearance. A chromosome has two units: DNA and proteins.
