Genomes of two famous mosquitoes have already been studied in genetics laboratories. The first was the mosquito genome that transmits malaria Anopheles gambiae, which was decoded in 2002. The second, that of Aedes aegypti, a mosquito that spreads Denge's disease, has not been completely decoded, but has just presented the 'first draft' of the code in Virginia Tech; they have discovered 80% of the genes that scientists expect. They are very different mosquitoes, with the greatest possible difference between two mosquitoes. In evolution, they were distributed 150 million years ago and have traveled very different paths. The explanation is in the repetition of the genetic code. The Aedes aegypti mosquito has many sequences that are repeated in the genome; the two mosquitoes have repeated sequences, but in all these repeats they account for 50% of the genome. In genetics, repetition of sequences is usually not useless, since the presence of the same information on several occasions often increases the complexity of the vibe. The decoding of the sequence is incomplete, but a large international team is working on it coordinated by the Virginia team. In addition to obtaining all the information, scientists intend to manipulate repeated sequences. In this way, they want to clarify the genetic relationship of the mosquito with the dengue virus.
