gel electrophoresis. This method relies on the fact that DNA fragments are charged, and it is an alternative to more expensive methods, such as X-ray crystallography, which was responsible for the discovery of the double-helix structure of DNA.
to determine the sizes of these unknown fragments, scientists usually plot a graph. On the x-axis is the distance traveled by each band in the ladder in millimeters, while on the y-axis is the size of each band. When the points are connected by a curve, the size of any band can be extrapolated from the curve after measuring the distance traveled by that band in millimeters.
Answer: Its measured with the use of gel electrophoresis.
Explanation: Scientists use a method known as gel electrophoresis to measure the lengths of DNA fragments. Electrophoresis works because fragments carry a small charge.
B. The reason we have the nomenclature (name) system we have is because it can reveal more about the animal. For example, it tells our genus and our species. Just the common name can apply to anything
