As a molecule moves through the plasma membrane it passes through. The phospholipid bilayer is arranged with the hydrophilic heads facing outward or inward into the aqueous solutions inside and outside the cell with the hydrophobic tails of the two layers pointing toward each other and excluding water from this area.
Hope this helps good luck
Answer:
Originally interphase of the cell cycle was called the "resting stage", since light microscopy could not detect any activities taking place within the cells. So it was thought that the cell is resting without carrying out any activities.

Answer:
The lagging strand undergoes a conformational change to make a hairpin structure, which allows DNA synthesis in the proper order.
The lagging strand must be synthesized in smaller units that are ultimately attached by the action of DNA ligase.
Explanation:
For DNA synthesis to occur on the lagging template strand, the lagging template strand is oriented in such a way that it forms an hairpin structure with the SSB proteins still in place.
This allows the structure to be in corformation with the rest replisome machinery and also allow the synthesis of DNA in the 5'-3' direction forming okazaki fragments in a discontinous backstitching mechanism which are then sealed toghether by the enzyme Ligase.
