- Jeffreys, Alec John. 1/9/1950 – ENGLISH GENETICIST. Alec John Jeffreys is a geneticist who is best known for the introduction of DNA analysis to forensic science. He discovered one of the most important tools for identifying human beings, genetic fingerprinting. This procedure analyzes each individual's genetic code.

Question: Why is DNA such an important area to know about? And it is has key importance in forensic biology – the sequences of DNA that vary from person to person is what we target when we want to use DNA to identify people. And finally by studying DNA, we have been able to characterise much about disease.

- Henry A. Gleason (botanist) Henry Allan Gleason (1882–1975) was a noted American ecologist, botanist, and taxonomist, known for his endorsement of the individualistic or open community concept of ecological succession, and his opposition to Frederic Clements's concept of the climax state of an ecosystem.

- Before the discovery and impact of DNA in the early 1980s, the advent of fingerprinting in the early 1800s and even before photographs were used in the late 1800s to capture images of killers on a victim's eyeballs, as was the case during the investigation of the world's first documented serial killer, Jack the Ripper, criminal investigators were using the science of forensics to solve crimes.

Forensic science Alec Jeffreys pioneered the use of DNA profiling in forensic science in 1984. He realized the scope of DNA fingerprinting, which uses variations in the genetic code to identify individuals. The method has since become important in forensic science to assist police detective work, and it has also proved useful in resolving paternity and immigration disputes.

- Lamarck was the first biologist to propose a mechanism for evolution. He proposed that organisms acquired features as they needed them. A giraffe would require a long neck because it strove to eat leaves high up in the trees, and birds that did not like swimming, but collected food in shallow water, would develop long legs and become waders.

- He concluded that the product of the Toll gene was involved in sensing pathogenic microorganisms and triggering host defense against them. Bruce Beutler and collaborators used a mouse model to search for a gene that activated innate immunity when exposed to a bacterial component (lipopolysaccharide; LPS).

Whatâs Better: A Motorhome or Trailer? There’s no contest when it comes to activities while on the road. The motorhome is the clear winner. Because in a motorhome, you don’t have to pull over for a bathroom break (except for the driver, of course!)… the potty is right down the hall.

Forensic biology Forensic biology is the application of biology to law enforcement. It includes the subdisciplines of forensic anthropology, forensic botany, forensic entomology, forensic odontology and various DNA or protein based techniques.orensic biology has been used to prove a suspect was at a crime scene, identify illegal products from endangered species, solve crimes by matching crime scene evidence to suspects, investigate airplane bird strikes, and investigate bird collisions with wind turbines.

What is a tool which allows scientists to identify unknown organisms? The structure and sizes of bones can be used by forensic scientists to identify unknown individuals. Different ethnic groups have different bone structures and there is stark … contrast between the bones of males and females.

The Origins of Information: Exploring and Explaining Biological Information Philosopher of science Dr. Stephen C. Meyer is examining and explaining the amazing depth of digital technology found in each and every living cell, such as nested coding, digital processing, distributive retrieval and storage systems, and genomic operating systems.n the 21st century, the information age has finally come to biology. We now know that biology at its root is comprised of information rich systems, such as the complex digital code encoded in DNA. Groundbreaking discoveries of the past decade are revealing the information bearing properties of biological systems.

What is Forensic DNA Analysis? Forensic DNA analysis is used to identify individuals using genetic samples. Basically, the system uses a set of identifying numbers to match two different samples. The concept was first designed by Sir Alec Jeffreys at the University of Leicester in 1985.

- Hydraulic door closers are devices that are installed at the top of the door and its frame. A hydraulic door closer helps close a door automatically. Hydraulic door closers are mainly used in commercial and office buildings, and utilize hydraulic based mechanism to automatically close the door. These door closers come in a number of different styles, but all work in the same exact way. For installation of the hydraulic door closer, you will require the door closer equipment, sealed tube, spring, fluid, and some basic handy tools. This article explains how the hydraulic door closer works.

molecular biology The term “molecular biology” itself was first used by the British scientist W. Astbury in reference to research on the relationships between the molecular structure and the physical and biological properties of fibrillar proteins, such as collagen, blood fibrin, and the contractile proteins of the muscles.

Brayton cycle Brayton cycle. The Brayton cycle is a thermodynamic cycle named after George Bailey Brayton that describes the workings of a constant-pressure heat engine. The original Brayton engines used a piston compressor and piston expander, but more modern gas turbine engines and airbreathing jet engines also follow the Brayton cycle.

- A Link for the Missing -- DNA Fingerprinting : The process of DNA profiling was developed by British geneticist Alec Jeffries in 1984 and has been instrumental in the forensic analysis of crime scene evidence leading to the conviction of perpetrators and the freeing of innocent convicts.NA profiles are encrypted sets of numbers that reflect a person's DNA makeup, which can also be used as the person's identifier. DNA profiling should not be confused with full genome sequencing. It is used in, for example, parent testing and criminal investigation.
