Transcription is a process that genetic information on the DNA copies into NA and the DNA acts as the template for the new molecules of NA. Transcription process begins with the DNA double helix unwinding as the hydrogen bonds holding the opposing bases breaks and the DNA strands are uncoupled.
The process occurs within the cytoplasm of a prokaryote and in the nucleus of eukaryotic cells. Transcription process consists of three steps; initiation, elongation, termination, and are regulated by transcription factors that include protein products of the genes. The protein products regulate at postranscriptional levels every time. Initiation of transcription begins with enzyme NA polymerase that identifies and attaches to DNA at the promoter and transcription of the DNA template starts. An initiation complex forms by association of 50 proteins different from each other required by NA polymerase II. NA polymerase synthesizes polynucleotides of NA from the template of DNA.

Indeed, the processes of life, both external and internal even, at the cellular and the molecular level, are governed by water. Without water, most living organisms suffer from what is known as water stress. This water stress can be due to the loss of water or dehydration. Desiccation is a special case of dehydration where drying takes place in air.
Alternatively, another form of water stress is due to the excessive accumulation of salts. This is relatedly called osmotic stress. Osmosis seeks to reduce this accumulation by moving fluids across a concentration gradient.

Origin of Eukaryotes Theory of Endosymbiosis The evolution of eukaryotes has no fossil record. However, from the study of modern organisms, biologists deduced their theory that eukaryotes evolved from prokaryotes through the endosymbiosis process.
The state of one species living inside another species, known as the host, is called endosymbiosis. Eukaryotes evolved from the Archaea domain of prokaryotes, whereby prokaryotic cell have engulfed aerobic bacteria instead of engulfing other prokaryotes. Membrane infolding is the first process that occurs in the development of eukaryotic cell. Around the nucleus, nuclear envelope is formed due to the inward folding of the plasma membrane. Later, attached to the nuclear envelope, endoplasmic reticulum is produced. The development process of mitochondria and chloroplasts completes the formation of eukaryotic cell.

Sands, Z. Grottesi, and M. Diffusion and Osmosis Experiment Lab eport The core purpose of the first experiment conducted in the lab was to study the principle of diffusion. The experiment aimed at analyzing the movement of molecules from a region of higher concentration towards lower concentration. Potassium permanganate crystals were dissolved in water to observe the process of diffusion.
The observations and results attained from the experiment indicated the movement of molecules which occurred due to molecular collisions, taking place more frequently in areas of higher concentration. Molecules present in a liquid or a gas move about constantly in random directions. During their movement, they bump into each other and bounce this way and that way. This random movement ultimately results in the uniform or even distribution of molecules. The tendency of molecules to spread out evenly throughout the space occupied by them is referred as diffusion.

These processes are dependent on the amount of the drug administered, the method of administration which affects the rate of absorption, biotransformation, and even excretion , and how the drug binds in the tissues. In essence, a drug's ability to transverse the cellular membranes depends on its solubility and molecular size and shape. The passive diffusion of the drug across cellular membranes depends on its lipid solubility as well as concentration gradients outside and inside the cellular membrane and the pH differences across the membrane.
Active transport of the drug occurs when the drug is actually moved by components of the membrane. This can allow a drug move against concentration and electrochemical gradients but it requires energy, can be selective, and can be inhibited by similar molecules. The absorption rate is influenced….

Found in both plant and animal products, such as olive oil, canola oil, peanut oil, and in some plant foods such as avocado Nutristrategy 10939, Phospholipids are major components of the cell membrane.
Phospholipids limit the passage of water-soluble compounds through the membrane, enabling the cell to keep its contents separate from the outside environment.

The other process is known as deplasmolysis and it involves cells adopting more water from the surrounding environment. These two processes can have an effect on cell permeability. These effects are realized either through turgidity or through flaccidity.
Flaccidity decreases the rate of permeability when the cell-membranes come into contact with hypertonic solutes. On the other hand, turgidity increases the rate of permeability when the cell membrane comes into contact with hypotonic solutions. The influence of temperature on a cell membrane can occur in two forms. The first influence occurs when the temperature is increased and the second influence occurs when the temperature is decreased. When temperature is increased, cell membranes react in valid manners. For instance, an increase in temperature can result in a melting impact of the cell membranes. This will in turn increase the rate of movement across cell membranes. This process might lead to the entry of foreign molecules into the cell. The foreign molecules can possibly cause cell damage.
Another effect of temperature on a cell membrane is that it can result in the destruction of peripheral or transmembrane proteins. Proteins are usually broken down by high temperatures. This unnecessary breakdown is a possible cause of destruction to the cell membranes. The increased activity increases temperature levels even further. This double action between cells increases the rate of cell destruction. Cell membranes become more rigid when temperatures decrease. The rigidness of the membranes can decrease the rate of permeability between cells. This development hinders activities between cells.
Lack of certain activities between cells will mean that some bodily functions will be affected. Low temperatures can lower the speed of permeability. When the speed of permeability decreases the growth of cells is hampered. In extremely low temperatures, permeability can stop leading to the shutdown of some cell functions. Molecule-size could be able to influence the rate of permeability in cell membranes. Different molecules have different sizes. This means that cells have to prevent or allow the entry of differently sized molecules. Each solute contains either small molecules or big molecules.
Sometimes the solute can have both big and small molecules. When cells are contained in solutes that contain small molecules, the level of permeability increases. Small molecules require less energy to permeate through cells. This makes it easier for cell membranes to accept these smaller molecules. The bigger molecules require more energy and resistance to enter though a cell membrane. Different solutes contain different levels PH levels and this translates to different permeability levels. Solutes that contain high PH levels increase the levels of activity within the cell membrane. High PH levels also lead to an increase in temperatures within the cell membranes.
