POLYMERASE OR REPLICASE ENZYMES: A polymerase enzyme catalyses the formation of a polymer and cellular polymerase enzymes of genetic interest are those that bring about the synthesis of one polynucleotide chain that is copy of another. A polymerase enzyme is called replicase enzyme when the copy of the polynucleotide chain so produced is inherited by daughter cells or viruses, that is, when the enzyme brings about chromosomal replication.
PROKARYOTIC DNA POLYMERASES: Three different DNA polymerases are known in E.Coli and other prokaryotes, of which DNA polymerase I and II are meant for DNA repair and DNA polymerase III is meant for actual DNA replication.

Mutations in the HEXA gene cause Tay-Sachs disease. The HEXA gene provides instructions for making part of an enzyme called beta-hexosaminidase A, which plays a critical role in the brain and spinal cord. This enzyme is located in lysosomes, which are structures in cells that break down toxic substances and act as recycling centers. Within lysosomes, beta-hexosaminidase A helps break

Enzymes is biologic polymer which can catalyse the chemical reaction. They can’t be destroyed, used up, or permanently changed while they involve in a reaction therefore the physical changes of enzymes will not be affected in a reaction. On the other hand excluding the catalytic of RNA molecules or ribozymes, enzymes are also made from protein. Additionally, every enzymes have their own specific function which makes them work more efficiently. Enzymes are also classify into several classification.

Catalysts help speed up reactions. Catalysts come from a certain molecular substance found in cells. These are called enzymes. Enzymes would temporarily bond to one or more reactants of a reaction and catalyze, meaning they speed up the process with lower activation energy needed. Enzymes provide a variety of functions such as cells using an enzyme to rid themselves of a poisonous substance (hydrogen peroxide) and also energy usage.

molecules attach to and the amino acids they carry are linked to form a polypeptide, this is translation.
Transcription is the process of making pre-mRNA using part of the DNA as a template. The enzyme DNA helicase acts on a specific region of the DNA molecule to break the hydrogen bonds between the bases, causing the two strands to seperate and expose the nucleotide bases in that region. This causes the specific region called cistron to unwind. One of the strands is used as a template to make an mRNA copy.The enzyme RNA polymerase moves along one of the two DNA strands, known as the template strand causing the nucleotides on this strand to join with the individual complementary nucleotides

the cow’s milk (whey & casein) along with the lactose (milk-sugar), allergies have immerged. The issue with lactose is that by the time most humans reach late childhood/adolescence scientists average 70% of us lose the enzyme that enable our bodies to break down this sugar. Without this enzyme active, our valves become backed up and our stomachs feel intense cramping which all means that you are indeed lactose intolerant.
Now, if you’re beginning to wonder about calcium, the next sentence will surely surprise you. The consumption of milk contributes to a deficiency in calcium. Vegans have been shown to have higher bone density than meat eaters of the same age, and countries that have

, vitamins do not provide any energy to the body. (Rolfes, Pinna, Whitney 322) Vitamins are also individual units, not complex chains of molecules. Vitamins also vary from energy yielding nutrients in the way that they are measured. Vitamins are usually measured in micrograms (µg) or milligrams (mg), while energy yielding nutrients are usually measured in grams (g). There are two distinct similarities between the two. This is that both vitamins and energy-yielding nutrients are available from foods, and they are extremely important in supporting life.
Vitamins’ primary role is being used in the formation of a co-enzyme. (Rolfes, Pinna, Whitney 325) The co-enzyme which is formed will then

locations in the genome of the cell called “origins”. A replication fork can be formed from the unwinding of DNA at the origin and the synthesis of new strands. By having the enzyme that synthesizes the new DNA by adding nucleotides that are matched to the original strand in addition to DNA polymerase, there are a several other proteins that are also associated with the fork and aid in the start and persistence of DNA synthesis. DNA is also able to replicate outside of a cell; this is called in vitro. When this occurs, DNA polymerases that are separate from the cell as well as artificial DNA primers begin DNA synthesis at known sequences in a template molecule. A specific target DNA fragment

species of Rhizobium, which are nitrogen-fixing bacteria. This signal attracts the bacteria to the roots, and a very complex series of events then occurs to initiate uptake of the bacteria into the root and trigger the process of nitrogen fixation in nodules that form on the roots (Figure 3).
Some of these bacteria are aerobic, others are anaerobic; some are phototrophic, others are chemotrophic (i.e., they use chemicals as their energy source instead of light) (Table 1). Although there is great physiological and phylogenetic diversity among the organisms that carry out nitrogen fixation, they all have a similar enzyme complex called nitrogenase that catalyzes the reduction of N2 to NH3

contamination. The antioxidant quality of honey also acts an anti-inflammatory agent on wounds. This effect had been demonstrated in burn injuries; in particular, partial-thickness burns wounds were “prevented from developing to full-thickness burn wounds by application of honey dressings” (Sharp, 2009, p. 70). Furthermore, honey increases the activity of the enzyme plasmin, which effectively digests fibrin that attaches slough to the wound surface without digesting collagen matrix needed for tissue repair. A study found that the increased plasmin activity is a result of honey inhibiting the production of plasminogen activator inhibitor (PAI), an enzyme that would have otherwise block the enzymatic

Levodopa, the most effective Parkinson's disease medication, is a natural chemical that passes into your brain and is converted to dopamine. MAO-B inhibitors help prevent the breakdown of brain dopamine by inhibiting the enzyme monoamine oxidase B (MAO B). This enzyme metabolizes brain dopamine (Mayo Clinic, 2013). Dopamine agonists mimic dopamine effects in the brain to lesson symptoms. Patients may also take a variety of medications like antidepressants to help with any psychological issues.

Despite claims to the contrary, humans have been consuming meat and other animal byproducts for a very long time (Derbyshire, 2012). Man has the ability to eat and digest meat to produce substance for his/her body. The human body creates an enzyme in the pancreas called trypsin that is secreted into the intestine which breaks down meat and make the proteins, fats, and other elements available for absorption. Herbivores do not have this enzyme in their system. Since milk is an animal byproduct it is easily digested by the

Why don’t the people of the United States put something together to support and guide the people who are suffering from depression?
One great risk for becoming depressed is if you smoke. Some scientists hold to believe that smoking may be linked to Depression. Tobacco smoke kills off an enzyme that is responsible for breaking down a nerve cell chemical that activates pleasure seeking behavior. So smokers have a high count of this nerve cell chemical and a very low count of the enzyme, which in turn may make

Phase II reactions consist of those enzymatic reactions that conjugate the modified xenobiotic with another substance. The conjugated products are larger molecules than the substrate and generally polar in nature (water-soluble). Thus, they can be readily excreted from the body. Conjugated compounds also have poor ability to cross cell membranes.” Some of the major transformation reactions in phase I reactions are oxidation, reduction, hydrolysis and acetylation. Some of the major transformation reactions in phase II reactions are sulfate conjugation, glucuronide conjugation, glutathione conjugation, and

N-nitrosamines are potent carcinogens in animals. These compounds can be synthesized from amines and nitrous acid under certain conditions. When nitrate is reduced to nitrite it can give rise to the formation of N-nitrosamine compounds that are an important class of chemical carcinogens for humans. However, nitrosamines occur in very few foods and at very low levels because of their chemical instability. It is important to note that the presence of nitrosamines in food products is generally not associated

The overall health of an individual is determined by examining several vital signs, such as body temperature, pulse rate, respiration rate, heartbeat, and blood pressure.
Our body controls the temperature within a narrow range by means of a process called thermoregulation. This is crucial as the degree of coldness or hotness greatly affects the enzyme activities and chemical reactions of the body. And to ensure regular functioning of such processes, body temperature is monitored with the help of a thermometer that is calibrated either in a Celsius scale or Fahrenheit scale.

While I believe if one chooses to end his or own life through physician assistance for reasons that they chose, the choice should be up to the individual. Physician-assisted suicide should be at one's discretion. “Assisted Suicide, also called Voluntary Euthanasia, is currently a contentious issue in many countries. Because Euthanasia is legal in a few modern democracies: the Netherlands, Belgium, and Switzerland. In the Netherlands, voluntary euthanasia has been legal since 1983, with some 3,000 people requesting it each year. In Australia, assisted suicide was legalized in the Northern Territory with the backing of a substantial majority of
