The molecular biology technique of reverse genetics can be useful for determining the function of a gene.
<h3>What is reverse genetics?</h3>
Reverse genetics is method use in molecular biology to determine gene function in an organism
The procedure in reverse genetics involves modifying or certain nucleotide sequences in the DNA coding for a functional gene and then observing changes to the phenotype of the organism brought about by the modifications.
Therefore, reverse genetics can be useful for determining the function of a gene.

The correct answer is a nutrient runoff.
Nutrient runoff is a major reason for eutrophication of surface waters, in which extra amount of nutrients, generally phosphorus or nitrogen, instigate growth of algae. Sources of nutrient pollution involve surface runoff from pastures and farm fields, emissions from combustion, and discharges from septic tanks.
In order to study the formation of cancer cells, you should study the life cycle of normal cells as cancer cells are abnormal cells.
Actually, Normal cells grow, divides and died after an interval of time. And when this process is break down, cancer cells begin to form. They are usually old cells which don't die after their life cycle.
Hope this helps!
