Document Summary
Genes provide the instruction for cell form, function, and complex behavior. Genome: the entire sequence of nucleotides in an organism"s dna provides a genetic program that instructs the cell how to behave. Each cell can carry out a variety of biological tasks, depending on its environment and its history, and it selectively uses the information encoded in its dna to guide its activities. The invention of light microscope led to the discovery of cells. The term (cid:498)cells(cid:499) is first used by robert. Hooke in 1665 to describe the tiny mass of minute chambers observed on the cork. Cell theory: all living cells are formed by the growth and division of existing cells, it implicates that living organisms do not arise spontaneously but can be generated only from existing organisms. Behaviors and structure of modern cell are all shaped and evolved from past cell, living under environments that are similar to its modern habitat.
