The most important decisions of the AU are made by the Assembly of the African Union, a semi-annual meeting of the heads of state and government of its member states. 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.
DNA replication also works by using a DNA template, the DNA double helix unwinds during replication, exposing unpaired bases for new nucleotides to hydrogen bond to. Gene synthesis, however, does not require a DNA template and genes are assembled de novo. DNA synthesis occurs in all eukaryotes and prokaryotes, as well as some viruses. The ...
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.
Glycol nucleic acid (left) is an example of a xeno nucleic acid because it has a different backbone than DNA (right). Xenonucleic acids (XNA) are synthetic nucleic acid analogues that are made up of non-natural components such as alternative nucleosides, sugars, or backbones. [1] [2] Xenonucleic acids have different properties to endogenous ...
RNA strands are created using DNA strands as a template in a process called transcription, where DNA bases are exchanged for their corresponding bases except in the case of thymine (T), for which RNA substitutes uracil (U). [4] Under the genetic code, these RNA strands specify the sequence of amino acids within proteins in a process called ...
A New Jersey state police DNA analyst said new technology was able to identify a victim's DNA on Paul Caneiro's jeans when prior methods could not. ... so no comparisons could be made,'' Schlenker ...

So-called hammerhead ribozymes are bits of genetic material that interrupt a DNA code at a particular point, and can be used to cut out genes that cause disease or harmful proteins. [109] 1988 – Polymer banknote – The development of the polymer bank note was made by CSIRO scientists led by Dr. David Solomon. Securency Pty Ltd, a joint ...
