Expressed Sequence Tag — Expressed Sequence Tags (EST) sind kurze DNA Sequenzen von meist 100–800 Basenpaaren Länge, die durch die teilweise Sequenzierung von cDNAs von deren 5 oder 3 Ende ausgehend gewonnen werden. Da cDNAs durch die reverse Transkription von mRNA… … Deutsch Wikipedia
Expressed sequence tag — An expressed sequence tag or EST is a short sub sequence of a transcribed spliced nucleotide sequence (either protein coding or not). They may be used to identify gene transcripts, and are instrumental in gene discovery and gene sequence… … Wikipedia
Expressed Sequence Tag — Marqueur de séquence exprimée Un marqueur de séquence exprimée, ou Expressed Sequence Tag (EST), est une courte portion séquencée d un ADN complémentaire (ADNc), utilisée comme marqueur pour différencier les gènes entre eux dans une séquence ADN… … Wikipédia en Français

expressed sequence tag — DNA sequence derived by sequencing an end of a random cDNA clone from a library of interest. Usually, tens of thousands of such ESTs are generated as part of genome projects. These ESTs provide a rapid way of identifying cDNAs of interest, based… … Dictionary of molecular biology
expressed sequence tag — (EST) a short (several hundred base pairs) DNA sequence obtained by randomly sequencing a clone from a cDNA library; the sequence thus represents a portion of an expressed gene and is sufficient to identify the gene to which it corresponds… … Medical dictionary
expressed sequence tag — Abbreviation: EST Partially sequenced cDNA clone. Because the read length of a standard DNA sequencing reaction is shorter than the majority of cDNA clones, full length sequence can only be obtained by further manipulations. For the purposes of… … Glossary of Biotechnology
expressed sequence tag — (EST) A partial gene sequence unique to a gene that can be used to identify and position the gene during genomic analysis … Dictionary of microbiology

Expressed sequence tag (EST) — A unique stretch of DNA within a coding region of a gene that is useful for identifying full length genes and serves as a landmark for mapping. An EST is a sequence tagged site (STS) derived from cDNA. An STS is a short segment of DNA which… … Medical dictionary
