An expressed sequence tag or EST is a short sub-sequence of a transcribed protein-coding or non-protein coding DNA sequence.

Expressed Sequence Tags (dEST): dbEST (Nature Genetics 4:332-3;1993) is a division of GenBank that contains sequence data and other information on "single-pass" cDNA sequences, or Expressed Sequence Tags, from a number of organisms.

Expressed sequence tag (EST) is STS derived from cDNA.

Expressed Sequence Tags (ESTs)
ESTs are short (200-500 nucleotides) DNA sequences that can be used to identify a gene that is being expressed in a cell at a particular time.
The Procedure: ...

expressed sequence tag (EST) A short portion of a cDNA molecule serving to identify a gene. Used in locating genes on chromosomes. See also: sequence tagged site.

Expressed sequence tag (EST)
A short strand of DNA that is a part of a cDNA molecule and can act as identifier of a gene. Used in locating and mapping genes.

Ethology: Study of animal behaviour under normal conditions.

Expressed sequence tag analyses of the annelid Pomatoceros lamarckii, recently published in BMC Evolutionary Biology, are consistent with less extensive gene loss in the Lophotrochozoa than in the Ecdysozoa, ...

EST: Expressed Sequence Tag
Flanking Region: For microsatellites, the flanking regions are the stretches of DNA outside the simple sequence tandem repeat (STR). These sequences are used as primer pairs.

Expressed sequence tags (ESTs) are STSs derived from cDNAs.
Sequencing Determination of the order of nucleotides (base sequences) in a DNA or RNA molecule or the order of amino acids in a protein.

1991 Sequencing of human expressed sequence tags begins in Craig Venter's lab, an attempt to capture the coding fraction of the human genome.

Any unique DNA sequence which can be used in DNA hybridization, PCR or restriction mapping experiments to identify that sequence. See expressed sequence tag and sequence tagged site.

clone seq Clones that are mapped onto the genome sequence include annotation units (e.g. BACS used to assemble the genome sequence), full length cDNAs and expressed sequence tags.
