2. Secondary biological databases, however, summarize the results from analyses of primary protein sequence databases. Secondary Databases: Those data that are derived from the analysis or treatment of primary data such as secondary structures, hydrophobicity plots, and domain are stored in secondary databases Primary data are usually collected from the source—where the data originally originates from and are regarded as the best kind of data in research. Biological Databases: 1. Primary databases contain primary sequence information (nucleotide or protein) and accompanying annotation information regarding function, bibliographies, cross-references to other databases, etc. There are two main classes of databases:DNA (nucleotide) databases and protein databases. Primary Databases • They contains biomolecular data in its original form. 6.2 Primary sequence databases 6.2.1 Introduction In the early 1980’s, several primary database projects evolved in different parts of the world (see table 6.1). 9 10. • A collection of – structured – searchable (index)-> table of contents – updated periodically (release)-> new edition – cross-referenced (hyperlinks) -> … Biological Databases serve a critical purpose in the collation and organization of data related to biological systems. It is an India's Largest Biological WebPortal Created for Providing Free Facilities to Research Scholars, Students, Teachers and Other Who Want to Work with Life Sciences.

NK BioSoft Provides Free Life Sciences, Agricultural Sciences Books, Journals, Softwares, Biological Documentries, Biological Calculators, Animated Tutorials and List of Major Biological Search Engines. They provide a computational support and a user-friendly interface to a researcher for a meaningful analysis of biological data. Literature databases include. c) record. a) entry. Primary databases store and make data available to the public, acting as repositories. Biological databases are centralised resources that contain representations of DNA and protein sequences and their associated information. DNA (nucleotide) Protein Each record in a database is called an. Databases and Different types of Biological Databases Definition: A collection of related data arranged in a way suitable for adding, locating, removing and modifying the data The database which store biological data is called biological database Eg: nucleotide sequence database b) PDB. 8 9. What is Primary Data? 3. Margaret Dayhoff developed the first protein sequence database called. d) Protein sequence databank. Primary data is a type of data that is collected by researchers directly from main sources through interviews, surveys, experiments, etc. Typesof BiologicalDatabases • On the basis of source: Primary Databases Secondary Databases 7. Various biological databases are available online, which are classified based on various criteria for ease of access and use. The primary sequence databases have grown tremendously over the years. c) Atlas of protein sequence and structure.
