European Nucleotide Archive or ENA

Question

Briefly explain European Nucleotide Archive or ENA?

Answer 1

European Nucleotide Archive (ENA)

A) Now overarches EMBL-Bank

B) Three ENA data tiers:

• Reads (sequencing machine output)
• Assembly (contigs and higher order structures created from overlapping sequence reads)
• Annotation (interpretations of biological function related to defined sequence regions)

C) Three ENA data types:

• Sample (biological sample undergoing experimentation)
• Taxon (source organism for the sample)
• Project (scope of the sequencing effort)

Captures and represents information associating to experimental workflows that are based around nucleotide sequencing.
