Intron Biology, Focusing on Group II Introns, the Ancestors of Spliceosomal Introns, eukaryotes and plants and subsequently found in bacteria and archaea. Group II introns display structural, functional and mechanistic similarities to eukaryotic pre-mRNA nuclear introns, which may have evolved from mobile group II introns. As in spliceosomal introns, the ribozyme of group II intron

Centromeres in Health, Disease and Evolution, at a specific region of each chromosome that is devoid of genes and characterized by heterochromatin. The underlying DNA is made up of a 171-bp tandem repeat known as alpha satellite, which is organized in a head-to-tail arrangement and spans up to several megabases in length. The centromere DNA is
