It provides all of the most commonly used nucleic acid and protein analysis tools and also provides access via the Internet to the public Entrez databases at the National Center for Biotechnology Information (NCBI). It is an integrated comprehensive sequence analysis program that runs on the Macintosh. MacVector™, from Oxford Molecular Group, Campbell CA, is one such computer package. ![]() It is evident by now that efficiently performing the above operations on thousands or millions of base pairs by hand is so difficult as to be impossible, and computer programs that do sequence analysis are becoming more and more ubiquitous in laboratories practicing molecular biology. Whether a researcher is working on a genome project, or is cloning and characterizing a gene of interest, the ability to manipulate, analyze, and annotate sequence data is becoming increasingly important.
