Explanation:
A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher level of nitrogen and nutrients in it.
Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in the water bodies and low oxygen content, the algae grows in slower rate. Besides, slower growth of algae may also affected by the acid rain that happens near Moose lake, which is harmful for algae growth due ti the presence of sulphur.
I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.
