What molecules located in the membrane assist with facilitated diffusion?
Usually proteins are the molecules doing the selection of what other molecules get into or out of a cell.
Principle of salting out method for genomic DNA isolation?
Th There are hydrophobic amino acids and hydrophilic amino acids in protein molecules. After protein folding in aqueous solution, hydrophobic amino acids usually form protected hydrophobic areas while hydrophilic amino acids interact with the molecules of solvation and allow proteins to form hydrogen bonds with the surrounding water molecules. If enough of the protein surface is hydrophilic, the protein can be dissolved in water. When the salt concentration is increased, some of the water molecules are attracted by the salt ions, which decreases the number of water molecules available to interact with the charged part of the protein. As a result of the increased demand for solvent molecules, the protein-protein interactions are stronger than the solvent-solute interactions; the protein molecules coagulate by forming hydrophobic interactions with each other. This process is known as salting out. ere are hydrophobic amino acids and hydrophilic amino acids in protein molecules.

What are the functions of genes and proteins respectively?
Genes are a segment of DNA which codes for a RNA or proteins. In any case, the first process is transcription of mRNA that will be then transported to cytoplasm. RNA may or may not synthesize proteins depending on the nature and message coded in it. mRNA usually interact with tRNA and ribosomes to make proteins.
Where does mRNA travele to in a cell?
mRNA is usually targetted to ribosomes, which transcribe the sequence into a protein. Some mRNA molecules do not code for proteins but instead interract with DNA in the nucleus.
What are facts about integral membrane proteins?
They are usually transmembrane proteins.

Proteins are usually large molecules made up of?
Amino acids

Are membranes often perforated by proteins that extend through both sides of the membrane?
Yes - usually to transport molecules of various types either into or out of the cell.

What is different between channel proteins and carrier proteins?
Both are integral membrane proteins involved in moving a molecule or ion across a membrane. Both have only one or a couple specific targets, so there are many kinds for specific molecules. The difference is how they accomplish this task. Carrier proteins transport molecules by changing shape. First, a molecule on one side fits the binding site, and by changing their configuration, the carrier can push the molecule to the other side of the membrane. A macroscopic analog might be a mailbox - a structural change of the transporter (the swinging door) facilitates the movement of a specific shape to the other side. Carrier proteins are affected by temperature and can be saturated (that is, they "max-out" at a rate of transport because there is a finite number of transporter molecules in the membrane and a configuration change is needed for every transport event). To keep the same analogy, the mail door can only swing so fast! Channel proteins usually transport ions or very small molecules down a concentration gradient, and are more like a hollow tube that can open or shut. They filter and transport molecules based on size and charge. A way to think about this is like a light switch - a on/off switch that allows flow of something (in this case, electricity) to the other side downstream in energy, perhaps doing work in the process. In almost all cases, channels cannot be saturated. If the tube is open, that specific type of molecule can go through without the channel having to change shape.
What is network Configuration?
The system network configuration refers to assigning a particular IP address by a network configuration window. The configuration window is usually invoked by selecting the network configuration sub menu from the setup command.
