4 Copyright OpenHelix. No use or reproduction without express written consent4 Introduction NCBI Viral Genomes Part of the NCBI Entrez-Genome collection Establishes a reference sequence for each viral genome Organizes data by taxonomy Provides tools to compare & analyze viral sequences Integrated with NCBI’s other databases

Replicates its genome & coat. Then breaks free to infect new cells.
