The cell membrane is also called as plasma membrane is a thin semi-permeable membrane that surrounds the cytoplasm of the cell. It is a double layer of proteins and lipids. The basic structure of cell membrane is called as the lipid bilayer. Phospholipids are the main component of the cell membrane. In addition, it also contains glycolipids and sterols. The lipid bilayer is embedded with proteins. The function of the cell membrane it regulates the entry of minerals, acts as a receptor, protects the cell, regulates the transport of substances in and out of the cell. It also plays a role in signalling and communication.

Answer from: Quest

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.
