Tiny one-celled organisms. The order of bases in a DNA molecule. The use of biologic al processes to manufacture products. The basic units of life. All living organisms are a collection of cells.
Identical twins are clones, as are colonies of bacteria that reproduce by simple cell division.
A sequence of bases that can form a double-stranded structure by matching base pairs. The long, spiralling m olecule that rchestrates the cell's daily operations and provides the genetic blueprint for the physical characteristics of all living organisms. When made up of two strands, the strands intertwine like a spiral staircase to form a structure called a doub le helix. Subunits, called bases, are the rungs of the staircase. A process which uses fragments of DNA to identify the unique genetic makeup of an individual.
