There are numerous write ups for this experiment available on the internet and elsewhere. I first experienced this lesson through UCSF’s Science and Health Education Partnership. I then tried it with Carolina Biological .
The estimates of the length of DNA in a human cell and the number of cells in the human body were taken from Wikipedia (from the Genome and Cell Biology articles).
2. A typical cell of any organism contains genetic instructions that specify its traits. Those traits may be modified by environmental influences. As a basis for understanding this concept:
e. Students know DNA (deoxyribonucleic acid) is the genetic material of living organisms and is located in the chromosomes of each cell.
5. The genetic composition of cells can be altered by incorporation of exogenous DNA into the cells. As a basis for understanding this concept:
a. Students know the general structures and functions of DNA, RNA, and protein.
