Replication fork Scheme of the replication fork. a: template‚ b: leading strand‚ c: lagging strand‚ d: replication fork‚ e: primer‚ f: Okazaki fragments Many enzymes are involved in the DNA replication fork. The replication fork is a structure that forms within the nucleus during DNA replication. It is created by helicases‚ which break the hydrogen bonds holding the two DNA strands together. The resulting structure has two branching "prongs"‚ each one made up of a single strand of DNA. These two

Social networking: For years‚ social networking sites didn’t exist‚ but yet people kept in touch. These days‚ with social networking sites becoming a part and parcel of our daily lives‚ there are advantages and disadvantages that come along with them. For example‚ you can make a friend from Timbuktu and on the flip side your account can get hacked and you can find yourself in a big mess. A recent research revealed that teenagers tend to hide the real stuff by using code language you may never understand

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be

What are the Advantages of Nuclear Energy? * Nuclear reactions release a million times more energy‚ as compared to hydro or wind energy. Hence‚ a large amount of electricity can be generated. Presently‚ 12-18% of the world’s electricity is generated through nuclear energy. * The biggest advantage of nuclear energy is that there is no release of greenhouse gases (carbon dioxide‚ methane‚ ozone‚ chlorofluorocarbon) during nuclear reaction. The greenhouse gases are a major threat in the

Nour Aljafari @55471 WRI 102‚ 11 am Nuclear energy: the future power supplier Ever since humanity has existed‚ there has been an increasing demand for energy as a means of survival‚ from its usage for cooking and warmth‚ all the way to electricity generation for production and agricultural activities. Today‚ over 80% of energy consumption comes from fossil fuels‚ which include coal‚ oil and natural gas (Irvine‚ 2011). However‚ those fuels are not renewable and won’t last for more than a

Nuclear energy is needed according to the demands of the energy that creates electricity. Nuclear energy plays an important role in the air pollution because it reduces the carbon dioxide emitted to the air. According to the new research that was done by The Food and Agriculture Organization (FAO) of the United Nations (UN)‚ about the uses of nuclear technology‚ the radioisotopes and radiation used in food and agriculture to reduce these figures that was done 2014-2016 that shows 795 million people

Is Nuclear Energy Safe? Atomic energy is the released by a nuclear reaction. Nuclear energy is an alternative for things that produce energy like coal‚ wind‚ or other natural resources. The use of nuclear energy in the world has had a huge impact on the economic qualities of countries. When countries use nuclear energy they are putting the people in risk of radioactive poison and cancer. Some people argue that nuclear energy is worth the risk if it saves money‚ but nuclear is too risky because
