Who Discovered Ribosomes

Who Discovered Ribosomes
Known as complexes of protein and RNA present in cells that have nuclei, ribosomes are important to the process in the genetic code expression called translation. These RNA complexes are responsible for messenger RNA (also known as mRNA) binding. Aside from this, it is also important to make the appropriate amino acids sequence. To know more about the functions and characteristics of the protein complexes, it is best if we start with learning the truth behind the discovery of ribosomes. Historical Background Who discovered ribosomes? The RNA complexes were observed and discovered by cell biologist from Rome George Palade in the mid-1950s with the use of a high-powered electron microscope. Because of his discovery, Palade received the Nobel Prize. However, the name was given in 1958 by scientist Richard B. Roberts. Palade identified ribosomes when he and collaborator Philip Siekevit analyzed the molecules that are connected to the endoplasmic reticulum in 1955. The two scientists found...

Who Discovered Diabetes

Who Discovered Diabetes
Diabetes, which is scientifically referred to as diabetes mellitus, is a severe medical condition that affects many people from almost all parts of the world. Common symptoms of this disease include increased thirst as well as frequent urination. Aside from its symptoms, causes and treatments, it is also quite interesting to look at other relevant details about the disease including who discovered diabetes. The Discovery of Diabetes Who discovered diabetes? Historical records show that diabetes has been recognized by the Egyptians way back to 1500 B.C. The ancient Greek physician named Aretaeus of Cappadocia coined the term ‘diabetes.’ Some time in the 1600s, the urine of patients who suffered from this particular type of disease was described as sweet. Later on, the term ‘mellitus’ was added by English doctor Thomas Willis in 1675. German scientist Oskar Minkowski and German physician Joseph von Mering successfully described the connection between the pancreas and diabetes. Additional...

Who Discovered Radioactivity

Who Discovered Radioactivity
Radioactivity has always been around since it is a natural part of the environment we have. It is said to be emitted by some of those things that we use everyday like the computer monitors and TV screens. Hospitals even use radiation for x-rays and other medical purposes. But who discovered radioactivity and made its usage possible? The Early Discovery of Radioactivity A Frenchman named Henri Becquerel is said to be the person who discovered radioactivity. In the year 1896, Becquerel got some naturally fluorescent minerals to be used in an in-depth experiment. The purpose of the experiment was to study the properties of x-rays. The properties were already discovered a year ago by Wilhelm Roentgen, and Becquerel wanted to further examine it. In the experiment, what Becquerel did first was to expose potassium uranyl sulfate to the rays of the sun believing that the energy of the sun will be absorbed by the uranium and then emit it outwards as x-rays. After exposing the potassium uranyl sulfate,...

Who Discovered The Constellation Virgo

Who Discovered The Constellation Virgo
Introduction The Latin origin of the word Virgo denotes a “virgin” or young woman. Presently, the autumn equinox is within Virgo. About 400 years from now it will move to Leo. Virgo is one of the biggest constellations in the sky, and contains many galaxies. It comes after Leo in the east. You can see it in the southern part of the sky in spring in middle latitudes of the northern hemisphere. History and Symbolism of Virgo Who discovered the constellation Virgo? Like several other major star formations, Virgo was known to the Sumerian and Babylonian astronomers. From them the knowledge of the sign passed on to the Egyptians, Greeks and other peoples in Asia Minor and the Mediterranean. Virgo is listed in a Babylonian astrology compendium known as the Mul Apin. These tablets are believed to be about 3,000 years old. The Mul Apin names Virgo as “absimu,”“the Furrow.” It was identified with the Babylonian and Akkadian goddess Shala. Virgo’s eastern stars including Spica were...
