Paternity Testing: Blood Types and DNA The process of DNA fingerprinting was developed by Alec Jeffreys in 1984, and it first became available for paternity testing in 1988. Before this sort of DNA analysis was available, blood types were the most common factor considered in human paternity testing.

The first insulin patient: where we all began Banting was one of the principal researchers who had discovered insulin – the first patient had received an injection in January of 1922 – but the scientists had not yet found a way to consistently produce the drug.

- ABO Blood Types. The most well-known and medically important blood types are in the ABO group. They were discovered in 1900 and 1901 at the University of Vienna by Karl Landsteiner in the process of trying to learn why blood transfusions sometimes cause death and at other times save a patient.

Who Invented Insulin? Dr. Frederick Banting of Toronto University discovered in his research that the hormone could be used to treat diabetes. Other researchers who helped him were Charles Best and Dr. James Collip. Early Research on Insulin. It was a Berlin student named Paul Langerhans who discovered insulin in the pancreas in 1869.Langerhans called it insulin which in German means islet or island, for that is what the hormones look like. Initially it was thought that insulin played a role in digesting food.urther Studies on Insulin. This discovery convinced scientists that insulin could be used to produce treatment for diabetes. Some of the early researchers who tried extracting it were George Zuelzer in 1906 and E.L. Scott of Chicago University in 1912.

Charles Drew, Inventor of the Blood Bank Charles Drew was also a honor student at McGill University Medical School in Montreal, where he specialized in physiological anatomy. Charles Drew researched blood plasma and transfusions in New York City, where he became a Doctor of Medical Science — the first African-American to do so at Columbia University. There, he made his discoveries relating to the preservation of blood.

Christopher Latham Sholes Christopher Latham Sholes (February 14, 1819 – February 17, 1890) was an American inventor who invented the first practical typewriter and the QWERTY keyboard still in use today. He was also a newspaper publisher and Wisconsin politician.ypewriters had been invented as early as 1714 by Henry Mill and reinvented in various forms throughout the 1800s. It was to be Sholes, however, who invented the first one to be commercially successful.

How long does it take to learn to touch type? Learning touch-typing over the years. The first man to touch type was Frank Edward McGurrin, a court stenographer who held the title of “world’s fastest typist” in the late 1800s and taught people to touch type on the side. Touch-typing was originally developed to help people use the keyboard on a typewriter.

Blood Human blood. The ABO blood group system was discovered in the year 1900 by Karl Landsteiner. Jan Janský is credited with the first classification of blood into the four types (A, B, AB, and O) in 1907, which remains in use today. In 1907 the first blood transfusion was performed that used the ABO system to predict compatibility.

Griffith's experiment Griffith's experiment discovering the transforming principle in pneumococcus bacteria. Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation.riffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been transformed into the lethal III-S strain by a transforming principle that was somehow part of the dead III-S strain bacteria.

Blood Typing and Crossmatching Blood typing is a laboratory test done to determine a person's blood type. If the person needs a blood transfusion, another test called crossmatching is done after the blood is typed to find blood from a donor that the person's body will accept.

AveryâMacLeodâMcCarty experiment The Avery–MacLeod–McCarty experiment was an experimental demonstration, reported in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty, that DNA is the substance that causes bacterial transformation, in an era when it had been widely believed that it was proteins that served the function of carrying genetic information (with the very word protein itself coined to indicate a belief that its function was primary).

genes and me Â» ABO blood group genes and me » blood type ABO. The ABO blood type was discovered by Austrian-American biologist Karl Landsteiner in 1900, who was awarded the Nobel Prize in 1930. Even today the major components in kits used to identify blood type are the same antiserums (anti-A and anti-B) that Landsteiner used over a century ago. If a given antiserum reacts with a drop of your blood and agglutinates, it means you are positive for that blood type.
