The answers to these questions are DNA replication and protein synthesis. Knowledge of the structure of DNA began with the discovery of nucleic acids in 1869; that genes control the synthesis of enzymes was understood in the 1940’s. In 1953, an accurate model of the DNA molecule was presented thanks to the work of Rosalind Franklin, James Watson, and, Francis Crick. Protein synthesis is the process by which individual cells construct proteins. “Both deoxyribonucleic acid or DNA and all types of ribonucleic acid or RNA are involved in the process,” (What Is Protein Synthesis, 2013.)
In the 70’s the creator of the first language in that era was Niklaus Wirth. His language was called “Pascal.” It was named after a mathematician named Blaise Pascal. The language was aimed to ease the building of compilers, and to lead teaching by forcing to a structured programming. However, one of the more popular programming languages in the 70’s was called “C.” It was created in 1973 by Dennis Ritchie. It was firstly destinated to program the UNIX operating system.
Agarose Gel Electrophoresis Cell Biology 12/3/2013 Introduction The purpose of this lab is to determine the size and charge of the molecules separated by the process called gel electrophoresis. Electrophoresis was introduced by Arne Tiselius in the 1940’s through moving boundary electrophoresis with his Tiselius apparatus, which was based off of electrophoresis through a free solution. Gel electrophoresis on the other hand, used an Agarose gel for its separation and wasn’t introduced to the public until the 1950’s. Gel electrophoresis is used for the separation of components based on their size, shape, and charge. This technique is highly used on DNA, RNA, and proteins.
Name General Chemistry 1411 Laboratory Techniques and Measurements May 16, 2013 Professor Frank Pishva Objective/Purpose: The objective of this lab, laboratory techniques and measurements is for us the student to learn about the unit systems and how it relates to measurements in mass, length, temperature, and volume. This lab purpose is to also help us learn how to combine units to determine density, conversions, and trying to become familiar with common laboratory equipment and techniques. Hypothesis/Theory: This lab is pretty self-explanatory. The only theory that could possibly occur is on data table 9, understanding the dilution process. As the dissolved sugar volume transfer increased, the mass will stay approximately the same due to the density of the water decreasing as the sugar water become less diluted.
If Neanderthals ever walk the earth again, the primordial ooze from which they will rise is an emulsion of oil, water, and DNA capture beads engineered in the laboratory of 454 Life Sciences in Branford, Connecticut. Over the past 4 years those beads have been gathering tiny fragments of DNA from samples of dissolved organic materials, including pieces of Neanderthal bone. Genetic sequences have given paleoanthropologists a new line of evidence for testing ideas about the biology of our closest extinct relative. The first studies of Neanderthal DNA focused on the genetic sequences of mitochondria, the microscopic organelles that convert food to energy within cells. In 2005, however, 454 began a collaborative project with the Max Planck Institute
The organization would expand to employ 130,000 people and end up totaling at a cost around $2 billion. An experimental reactor pile was tested in 1942, at the University of Chicago. It generated the first self sustaining-nuclear reaction. Following the reactor pile test, the Manhattan Project established a top secret laboratory at Los, Alamos, New Mexico, to design and build the atomic bomb. At the time they also constructed other secret facilities to create weapons grade plutonium.
In an ever advancing world, we are constantly being bombarded with new technology. One of the most life changing pieces of technology was the personal computer. Throughout the past decade computers have advanced even more and almost everyone has one of their own or access to one at places like a school or library. With the ability to obtain vast amounts of information so simply with just a few clicks, the computer seems like such a great object. Although the computer is fantastic in many ways and has helped improve civilization’s way of living, have people all over the world come to rely on this device too much?
According to Kevin, lasers and lights could be replaced with this technology. (Interview) The compound semi-conductors are able to perform more tasks because of their physical structure. They are used in especially violent environments, such as jet engines, or space craft, withstanding variances of temperatures. In cell phones LEDs, and other devices advancements have been made due to compound semi-conductors. (Compound Semi-Conductor Foundation, Online '01) In the future, advancements that help cost-efficiency the compound semiconductor could be the viable option to replace the silicone semi-conductor in computers and microchips which will obviously revolutionize the
In 1970, the Federal Bureau of Investigation developed a computerized automated fingerprinting system, called AFIS, which is still in use today. Sir Alec Jeffreys developed the first DNA profiling technique in England in 1985. Fhe FBI's combined DNA index system, or CODIS, which allowed different crime labs and departments to share DNA information, was created in 1990. In the early 2000s, the Scanning Kelvin Probe was developed by scientists at the Swansea University in the United Kingdom. The probe uses electric voltage to "see" latent fingerprints, even on surfaces that have been wiped
Research and development will always be the backbone of scientific research. Since the early 1980s science has evolved in a way that is untouched by any other advancement in the modern world. We have been witness to the creation of computers, smartphones, advanced cars, television and in the medical field the cures and treatments of many diseases. New medicines have evolved to create a better lifestyle to live by and surgical procedures that once were just dreams of the delusional. All of these new procedures and inventions
