An eye has a highly specialized retina that senses light and processes the signals using dozens of diverse types of neurons instead of photographic film. An eye is exceedingly complex in that its origin has been a cause of célèbre for a long period among intelligent and creationists design advocates.

Every strand is composed of nucleotides, a sequence of bases. A base can be one of the four chemicals, adenine, thymine, cytosine, or guanine. The two DNA strands are connected to every base. Bases can only bond with each other as follows: Guanine (G) can only bond

They are genetically modified through injection of various chemicals or connecting them to different species in order to create a whole new breed. This results to plants that look bigger and healthier on the

The analysis is important and has been widely applied in the medical field especially with the human genome project that successfully made it possible to understand the whole human genome. Genomics were initiated by Fred Sanger and in his studies he sequenced the genome of viruses.
