What variation in the moth example was natural selection acting upon?

hi there,

your answer your response to this

Adaptations are the result of evolution in different types of  living organisms. This process occurs amazing  through out the gene mutation, but it takes a very long period in time in the  process . Adaptation occur to help species survive it and in the ecological balance of life.  adaptations are physical features of an organism that adapted through time. An example The  birds for hunting, and bears to protect them from low climate areas so they can  hide.

i hope this helps you out

have a great evening

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.
