An article published in the magazine “GigaScience” reports a DNA sequencing of Architeuthis dux, commonly known as giant squid. A team of researchers led by Rute da Fonseca of the Danish University of Copenhagen employed a number of genetic techniques to obtain the complete genome of this cephalopod, one of the largest in the history of this group of invertebrates. Its DNA is very large with its 2.7 billion base pairs of DNA, approximately 90% of the size of the human genome. Among the interesting results there’s the discovery of over 100 genes that encode proteins of the protocadherin family, important in the correct connectivity of a complex brain.
