Biotechnology

Stem Cells

• a toxic chemical that causes damage to an organism's DNA

• a simple cell in the body that is able to develop into any one of various kinds of cells (such as blood cells, skin cells, etc.)

• The basic unit of structure and function in living things. Cells can make products, be products themselves, or be used to do jobs.

Proteins

• DNA manipulation of cells or organisms- Genes are added, deleted or change

• Essential molecules within cells. (Usually a desired product made by cells) Amino acids are the building blocks of proteins.

• Unique DNA molecules that provide blueprints for cells to make proteins or carry out other life functions.
