Gel electrophoresis is used to separate DNA, RNA, and protein molecules by using an electric field. Protein gel electrophoresis is similar to agarose gel electrophoresis, but runs protein bands instead. The technique of protein gel electrophoresis uses cross-linked polymers of acrylamide (which is a neurotoxin and requires careful handling) or polyacrylamide to separate proteins and small nucleic acids. This technique takes longer than the agarose gels used to separate larger nucleic acids. Also…

The History of the Development of the Four Fundamental Forces Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force. Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…

that you can use salt water to make a light bulb shine? It sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. What happens is the…

Prize for his study and finding of the charge of an electron. His findings greatly helped the scientific community by contributing to the Atomic Theory of Matter, which states that all matter is made out of atoms. Millikan found the charge of an electron by performing an experiment, which we now call Millikan’s Oil Drop Experiment. The Oil Drop Experiment was…

Early Atomic Experiments Joseph John Thomson conducted an experiment that is known today as the CRT Experiment. The outcome of this experiment was JJ’s discovery of the electron. CRT is an acronym for Cathode Ray Tube, this gives a broad concept of what the experiment is about. The basic components of the experiment include, a glass cylindrical tube with most of the air inside vacuumed out of it, and inside the tube is Electrode for each side. One of the Electrodes is negative and entitled the…

also be a variety of different minerals which are referred as salts. These salts include sodium, calcium, magnesium, potassium, chlorine, phosphorus and others. These salts all possess electric charges, the number of positive and negative charged particles are equally balanced. Therefore, it has no resultant charge which is neutral. The correct balance of salts is crucial to maintain the proper functioning of the human body as salts not only control your fluid balance, but it also controls how…

xe- ↔ 2 MxWO3 (deep blue) ------------- Equation (1) An electrochromic system consists of an ion-containing material (electrolyte) that is of close proximity to the electrochromic layer and the transparent layers for the setting up a distributed electric field. Ions are shuttled back and forth within the electrochromic layer when potential is applied. Typically, an electrochromic system is fabricated from five layers which comprises of two transparent conductors, an ion conductor or electrolyte,…

kite experiment) helped in building the connection between the electricity and lightning. In his experiment with kite included a kite with the key tie to the end of kite, which is connected to the Leyden jar. When the lighting struck the kite, the electric current travel down the string through the key and into the Leyden jar. We wonder that “what is there in Leyden jar”. It is an old fashioned battery and consist of the glass jar, wrapped in, with lead foil lining. Going into the jar is a metal…

The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which…

through many different contradicting testimonies. Subsequently, scientists have created many theories for the origin of the lights, involving numerous examples from piezoelectricity which is the he ability of certain materials to generate an electric charge in response to applied mechanical stress.
