In the quaternary structure, there is a particular shape of a complex, aggregate protein, defined by the characteristics three dimensional arrangement of its constituent subunits, each a polypetide.With the 4 levels of structure in a proteins are essential to the cell membrane.In Interphase the nucleus starts to uncoil and the nuclear membrane is still intact.
In the secondary structure, there is a localized, repetitive coiling or folding of the polypetide backbone of a protein due to hydrogen bond formation between constituents of the backbone.
In the tertiary structure, there are irregular contortions of a protein molecule due to interactions of side chains involved in hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges.

The hydrophilic heads make up the outside bilayer and come in contact with aqueous solutions that are inside and outside of the cell.
The hydrophobic tails are the interior of the cell membrane and keeps aqueous solutions away from it.Although it has two types of proteins the intergral protein has the more important role. In conclusion this information shows the importance of phospholipids and proteins of the cell membrane.Since the laboratory assistant didn’t label that solution’s correctly it would be more difficult to find out which ones contain a certain amount of sucrose.When the phospholipid is created a bi layer is formed constaining a hydrophillic head and a hydrophobic tail.Proteins are paramount in the function of the cell membrane.(The daughter chromosomes move to the opposite side of the cell.) In Telophase two new cells starts to form. A furrow is formed and the cell is pulled into two.The nuclear envelope reforms for both daughter cells. Once the process of Mitosis is over two new cells are formed and the process starts all over again.A) Phospholipids are essential to the components to the cell membrane.Phospholipids consists of two hydrophilic heads and a hydrophobic tail.In Metaphase the spindle fibers attach to the centromeres of the chromosomes and the chromosomes line up at the metaphase plate.In Anaphase the spindle fiber get shorter and the centromeres splits.
