 Locating Genetic Information


The cell is the basic unit of life. There are two kinds of cells: prokaryotes and eukaryotes. Prokaryotes don't have a nuclear membrane - a membrane that surrounds the nucleus allowing only certain chemicals to pass through. Eukaryotes, like the cell pictured below, do have a nuclear membrane and other small cell organelles that prokaryotic cells often lack.

Sometimes a cell can be an organism by itself (yeast, bacteria). Other organisms - humans, trees, sharks - are multicellular. These organisms are made up of many specialized cells (muscle, skin, xylem, brain cells ... ). All of your genetic information is stored inside of almost every single one of your cells. Humans contain more than 75,000,000,000,000 cells.

Next, find out where the cell stores genetic material.
