The African and Malagasy Union (AMU) or the Union Africaine et Malgache (UAM) in French was a former intergovernmental organization created to promote cooperation among its members. The organization derives its name from the name of the continent of Africa and from the former Malagasy Republic, now Madagascar.
The AU's secretariat, the African Union Commission, is based in Addis Ababa. The largest city in the AU is Lagos, Nigeria while the largest urban agglomeration is Cairo, Egypt . The African Union has more than 1.3 billion people and an area of around 30 million km 2 (12 million sq mi) and includes world landmarks such as the Sahara and the Nile ...
In 1995, the idea for DNA-based memory was proposed by Eric Baum [14] who conjectured that a vast amount of data can be stored in a tiny amount of DNA due to its ultra-high density. This expanded the horizon of DNA computing into the realm of memory technology although the in vitro demonstrations were made almost after a decade.
Humans do not generate all of the brain cells they will ever have by the age of two years. Although this belief was held by medical experts until 1998, it is now understood that new neurons can be created after infancy in some parts of the brain into late adulthood. [480] People do not use only 10% of their brains.
1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
Then, the DNA cassettes are exposed to the YAC vector, which drives the process of homologous recombination, thereby connecting the DNA cassettes. Polymerase Cycling Assembly and TAR technology were used together to construct the 600 kb Mycoplasma genitalium genome in 2008, the first synthetic organism ever created. [ 11 ]

This technology entails the joining of DNA from different species and the subsequent insertion of the hybrid DNA into a host cell. One of the first individuals to develop recombinant DNA technology was a biochemist at Stanford by the name of Paul Berg. [7] In his experimental design in 1974, he cleaved (cut into fragments) the monkey virus SV40.
