Cells are the basic units of life. In this practical, you will examine the simple unicellular organism, Paramecium claudata, to demonstrate that individual cells can undertake all of the essential functions of life. All of those essential functions are mediated by various proteins, which, in turn, are encoded by the cell’s genetic material, DNA (deoxyribonucleic acid).
According to the Central Dogma, biological information is encoded by DNA and DNA is the blueprint for all life. It is a self replicating molecule that encodes proteins. Proteins are the basic physical machinery of cells, and cells are the fundamental structural and functional units of life. Hence, DNA controls life.
This practical has two components: (i) introduction to micropipettors, and (ii) microscopic observation of Paramecium.
