Why is the work of alfred russell wallace considered when discussing the theory of evolution? a. he was a british dog breeder who worked on artificial selection experiments in the same way mendel worked on sweet peas to determine inheritance. b. his work is not considered, as he was mistakenly credited with the theory of natural selection. c. he was an english naturalist who had arrived at many of the same conclusions as darwin through his own research in the amazon. d. he was well known and gathered even more evidence to support evolution than darwin, though from the amazon rather than the galapagos.

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.
