How is DNA fragment length measured?

Biology

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.

Hope this helps :)

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.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
koban [17]
I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.
