Which of the following functions is NOT associated with the spinal cord?
(A) It provides a two-way conduction pathway for signals between the body and the brain.
(B) The spinal cord is a major integration center for reflexes.
(C) Through the spinal nerves that attach to it, the spinal cord is involved in sensory and motor innervation of the entire body inferior to the head.
(D) Through the cranial nerves that attach to it, the spinal cord is involved in sensory and motor innervation of the head and neck.
(E) All of the statements are functions attributed to the spinal cord. There are no exceptions.

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.
