Description
The DNA molecule from a single human chromosome is about 4 cm long and the length of DNA in an individual is about 200 times the distance from the earth to the sun. Isolated DNA in a test tube is also a long, stiff molecule. When alcohol is added to a DNA solution, the DNA fibers precipitate and can be spooled onto a glass rod. This feature of DNA is
illustrated in the exercise. The spooling phenomenon is also used by the student to study the double-stranded nature of DNA and to investigate the effect of breaking DNA into small pieces with the enzyme DNAse.
