Because a nanometer is one billionth of a meter, and a millimeter is one thousandth of a meter, a nanometer is one millionth of a millimeter. How is a ribosome an example of a biological nanosystem? A nanosystem manufactures components at the molecular level. Because a ribosome manufactures protein molecules from amino acids in a directed fashion, it can be described as a biological nanosystem. Critical Thinking: How might nanotechnology impact the field of cell biology in the future? Sample answer: Because nanomaterials are minuscule when compared to the size of a cell, nanosys- tems could function within a cell, allowing biologists to manipulate the internal workings of a cell.
