The discovery of DNA is attributed to the research of three scientists in 1951; Francis Crick‚ Maurice Wilkins‚ and James Dewey Watson. They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals

Sperm Sexing In Cattle Sperm sexing is an area of bovine reproduction technology which is utilised to improve and increase farm productivity by taking advantage of the difference in the value of males and females in the dairy and beef industry. It is a useful and accurate application in which the desired X- or Y- bearing chromosome is sorted and stored in a straw for later use. Selection of the desired sex is a potential determining factor to increase the genetic progress and farmer profitability

Scientists have developed the ability to retrieve and preserve individual gametes and embryos by way of cryopreservation‚ a technique that involves preserving biological materials at very low temperatures outside the body for years. . This field of in vitro fertilization (IVF)‚ worth $2 billion annually in the United States‚ has forced us to think about human tissue in ways never before thought possible. These advancements have meant that it is now possible for children to be conceived after the death
