Sequence Viewer can display notes to the user, and can label sections of DNA sequences.Ī “note” in this context is text that is displayed to the user before the first DNA In sequences must be indicated with a “-“ symbol so the that all of the sequences If they are divided into segments, the segments do not have to the same length. The DNA sequences do not have to be divided into segments, and Second, eachĭNA sequence is preceded by a line labeling the sequence, and this line must begin Sequences must be aligned and each sequence must be the same length. The input file must have the following characteristics.

Of these text files this, start Sequence Viewer, go to the menu, and select The sequences toĭisplay are stored in text files which Sequence Viewer opens and reads. Sequence Viewer is a tool for viewing and comparing DNA sequences. Delete the file to “uninstall” the program. Once you have downloaded the file, unzip it, and click on SequeceViewer.exe Sequence Viewer requires no formal installation. (It will be listed under "Pick updates to install.") To do this, open MicrosoftĮxplorer, go to the menu and select. NET already installed on your computer, the easiest way to install NET is already installed and you do not need to install it again. NET Framework 2.0 listed (or a more recent When that window appears, scroll through the list You can checkīy clicking 'Start' on your Windows desktop, selecting 'Control Panel', and then double-clicking Has a recent version of Windows, it probably already has. Operating system used to build and run Windows-based applications. NET Framework is a component of the Microsoft Windows Sequence Viewer runs on the Microsoft Windows operating system. Sequence Viewer does not search online databases, align sequences, or construct phylogenies.Īll of these functions will need to be performed by an instructor using other software.Displays labels marking active sites, exons, or other regions of a gene selected by.Counts the number of nucleotide differences between DNA sequences.Translates DNA sequences into amino acid sequences.Sequence Viewer performs the following functions: Is intended for introductory biology students with no previous genetics training. Is an easy-to-use computer program for viewing and compare DNA sequences. Sequence Viewer for Students (Sequence Viewer) Most programs for manipulating DNA sequences have been written for researchers, andĪre difficult for students to use. This makes them difficult to view and compare. Unfortunately, the DNA sequences of most genes are inconveniently long, and Is used, and how DNA sequences evolve, they need to study DNA sequences of actual In order for students to understand how DNA stores information, how this information
