In 1831‚ Charles Darwin‚ proposed a theory of evolution occurring by the process of natural selection. This has come to be known as the Theory of Natural Selection. Darwin worked on his theory for 20 years and after learning that Alfred Russel Wallace‚ another naturalist‚ had developed similar ideas‚ the two made a joint announcement of their discovery in 1858. Darwin published ’On the Origin of Species by Means of Natural Selection’ in 1859‚ 28 years after he proposed his theory of natural selection

Genetic Engineering is the changing of an organism’s genetic‚ or hereditary‚ makeup to get rid of unwanted characteristics or to make wanted new ones. Genetic engineering is used to increase plant and animal food production. It is also used to help dispose of industrial wastes‚ to diagnose disease‚ improve medical treatment‚ and produce vaccines and other useful drugs. Genetic engineering techniques include the selective breeding of plants and animals‚ and hybridization‚ which is the reproduction

The Importance of Genetics People fear what they do not understand. If only society would take time to understand the facts of genetics‚ they would grasp the concept of the important role it plays in our everyday life. With our coming into the 21st century we must take advantage of the technology we develop‚ in order to continue survival with all of the new obstacles we uncover everyday. Every time we take a bite of an apple‚ or taste the juices of a vegetable‚ we think of how good it is or how

What is the role of genetic testing ? - Genetic testing for Hemophilia A&B is to check for mutations within the genes. DNA testing would be the most accurate test for identifying carriers. A blood sample from a male family member with hemophilia is checked first. Then‚ a blood sample from the woman that is asking for is obtained and

bioengineering have helped us develop a better understanding of the origins from which humans and other living creatures spur. The discovery of the Deoxyribonucleic acid (DNA) is the key to all bioengineering. The DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. An allele is one of two or more forms of the DNA sequence of a particular

Genetic Engineering: Friend Or Foe Genetic engineering is the artificial manipulation‚ modification‚ and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms. Humans have altered the genomes of species for thousands of years through artificial selection and more recently mutagenesis. Genetic engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed since the 1970s. The term "genetic engineering"

Vincent Willem Van Gogh was born 30th March 1853 in Zudert‚ Netherlands. He is generally considered the greatest Dutch painter after Rembrandt ( known for his Baroque style painting )‚ though he had little success during his life time‚ Van Gogh produced all of his work (some 900 paintings and 1100 drawings ) during a period of 10 years before he succumbed to mental illness ( possible bipolar disorder) and committed suicide. His fame grew rapidly after his death especially following a showing of
