and other biological sequences such as amino acids. It simplifies the import and assembly of genetic sequences from any organisms with the use of an automated aligner. This editing process can be depicted into two subcategories: "Primary Structure Editor" and "Secondary Structure Editor." Comprehensively, this allows the necessary make up for the "Phylogenetic Treeing." The software also allows the visualization of these biological sequences which gives the user a more in depth experience and interaction. This is particularly necessary when comparing phylogeny data from various organisms.

Introduction

From the authors' own description,

The ARB (from Latin ''arbor'', tree) The ARB program package comprises a variety of directly interacting software tools for sequence database maintenance and analysis which are controlled by a common
graphical user interface The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows User (computing), users to Human–computer interaction, interact with electronic devices through graphical icon (comp ...

A phylogenetic tree visualized in the main window can be used for data access and visualization. The package comprises additional tools for data import and export, sequence alignment, primary and
