රාත්‍රියට යට ඇදුම් ඇදගෙන නිදා ගත්තොත් වෙන දේ දන්නවද?

Life opens with a description of the origins of life in the ancient sea. Unicellular organisms swim around and mingle. These are explained as the first life forms on earth, the organisms that are at the base of the tree of life. More specifically, the cell is described as the fundamental unit of life, a unit that has persisted from the origins of life to this day. The division of a human body cell is shown, magnified to expose detail; each daughter cell carries the same information, and has the same structure as the parent. The DNA inside the cell, shown in the form of chromosomes, is what directs cell division and all other processes that begin and sustain life. High-resolution photography reveals the detailed, intricate structure of the chromosome.
