How big is RefSeq?

How big is RefSeq?

RefSeq is limited to major organisms for which sufficient data are available (more than 66,000 distinct “named” organisms as of September 2011), while GenBank includes sequences for any organism submitted (approximately 250,000 different named organisms)….RefSeq.


What are the benefits of RefSeq?

RefSeq sequences form a foundation for medical, functional, and diversity studies. They provide a stable reference for genome annotation, gene identification and characterization, mutation and polymorphism analysis (especially RefSeqGene records), expression studies, and comparative analyses.

What is the difference between GenBank and RefSeq?

What is the difference between RefSeq and GenBank? GenBank sequence records are owned by the original submitter and cannot be altered by a third party. RefSeq sequences are not part of the INSDC but are derived from INSDC sequences to provide non-redundant curated data representing our current knowledge of known genes.

What are RefSeq identifiers?

The RefSeq ID is a unique identifier given to a sequence in the NCBI RefSeq database. The RefSeq database is a curated, non-redundant set including genomic DNA contigs, mRNAs and proteins for known genes, and entire chromosomes. These variables are used to make the Web link to the RefSeq database.

Is RefSeq a primary database?

The RefSeq collection is derived from the primary submissions available in GenBank. GenBank is a redundant archival database that represents sequence information generated at different times, and may represent several alternate views of the protein, names or other information.

How do I download RefSeq?

To use the download service, run a search in Assembly, use facets to refine the set of genome assemblies of interest, open the “Download Assemblies” menu, choose the source database (GenBank or RefSeq), choose the file type, then click the Download button to start the download.

What is a RefSeq protein?

A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.

Why Refgene database is significant?

The RefSeq database provides a critical foundation for integrating sequence, genetic and functional information, and is used internationally as a standard for genome annotation. The collection is curated on an ongoing basis by collaborating groups and by NCBI staff.

What are RefSeq transcripts?

What is a RefSeq quizlet?

A RefSeq is a single, complete, annotates version of a species sequence that can be accessed for bioinformatics studies: Indicate the correct order for one round of infection by bacteriophage T4. 1.

What is GenBank database?

GenBank® is a comprehensive database that contains publicly available nucleotide sequences for more than 300 000 organisms named at the genus level or lower, obtained primarily through submissions from individual laboratories and batch submissions from large-scale sequencing projects, including whole genome shotgun ( …

What is the purpose of the RefSeq sequence collection?

The Reference Sequence (RefSeq) collection provides a comprehensive, integrated, non-redundant, well-annotated set of sequences, including genomic DNA, transcripts, and proteins. RefSeq sequences form a foundation for medical, functional, and diversity studies.

How does the complete accession format work in RefSeq?

2 The complete accession format consists of the prefix followed by the INSDC accession number that the RefSeq record is based on followed by the RefSeq sequence version number. 3 The complete accession number format consists of the prefix, including the underscore, followed by 6 or 9 numbers followed by the sequence version number.

Which is the best description of the RefSeq select dataset?

The RefSeq Select dataset consists of a representative or “Select” transcript for every protein-coding gene.

Which is an example of a RefSeq status?

The RefSeq status (e.g., REVIEWED etc) is either indicated by the collaborating group, or is inferred based on the supplied annotation. Genome Assembly & Annotation Pipeline NCBI is providing annotation for some assembled genomic sequence data including human, mouse, rat, honey bee, chicken, chimpanzee (and others).
