The image shows two types of diffusion movements in the phospholipid membrane. Lateral diffusion is the lateral movement of lipids within the membrane, and transverse (flip-flop) diffusion is the movement of lipids from one side of the membrane surface to the other. Membrane proteins also move through lateral and transverse diffusion. Which of the following statements regarding membrane protein diffusion is true?

-The orientation of protein polar regions will remain the same after lateral diffusion.
-The orientation of protein polar regions will remain the same after transverse diffusion.
-Lateral diffusion of proteins will disrupt the hydrophobic interactions within transmembrane proteins.
-Lateral diffusion of proteins will disrupt protein interactions with the extracellular matrix and cellular cytoskeleton.

a.) a destruction fo cells by viral reproduction

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.
