This database is recommended if you are not considering variations represented by alternate loci.
Mitochondrion and plastid genomes are also included where applicable.Īlthough sequences in this database are completely covered by the Refseq representative genomes database, it does not contain the alternate loci and thus avoids sequence redundancy introduced by including alternate loci. These are Refseq representative genomes from primary chromosome assemblies (i.e., no alternate loci) for many eukaryotic organisms. Genomes for selected eukaryotic organisms (primary assemblies only): This contains all RNA entries from NCBI's Reference Sequence collection
Mitochondrion genomes are included where applicable. For other species, genomes from diverse isolates of the same species may be included. For the eukaryotes, only one genome is included per species (However, alternate loci of eukaryotic genomes are included where applicable). This database contains minimum redundancy in genome representation. These genomes are among the best quality genomes available at NCBI. This database contains NCBI RefSeq Reference and Representative genomes across broad taxonomy groups including eukaryotes, bacteria, archaea, viruses and viroids. This contains mRNA only from NCBI's Reference Sequence collection
