Which best describes the advantage of pest resistance?

The option that best describes the advantages of pest resistance is:

Farmers do not have to use harsh chemicals to save their crops.

Explanation:

A pest can be described as an animal particularly an insect which damages plants or crops. Formerly, farmers had to use chemicals to kill insects which attacked the crops. These chemicals would affect the plants also. The insects also developed resistance for these chemicals after a short period of time.

Now, the techniques of biotechnology have made it possible to make crops which have pesticide resistant genes in them. These crops are hence not affected by the pesticides.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
