Cells and Natural Selection

Paper Summary:

A two-part paper which defines what cells are and explains their molecular content. It links these points with how single celled organisms pass through a series of stages as they grow, replicate their DNA, prepare, divide up the copies of the DNA molecules and divide again. The paper then moves to Darwin's theory of 'natural selection' and DNA tampering.

From the Paper:

"A cell is a small, membrane-bound compartment that contains chemicals and molecules. Although all living organisms are made up of cells, all organisms are not alike. The structure of cells is a very important step in understanding how an organism's life is supported. Cells are the building blocks of organisms. Some organisms consist of a single cell, while other organisms are made up of multiple cells. A bacterium, for example, is a single-celled organism, while a human is a multicelled organism."
