(STS) A short (200- to 500-bp) DNA sequence that has a single, unique occurrence in an organism's genome, and whose location and base sequence are known.
Short cDNA sequences of regions that have been physically mapped. STSs provide unique landmarks, or identifiers, throughout the genome. Useful as a framework for further sequencing.
A unique, sequence-defined landmark in the genome that can be detected a specific PCR reaction.
Short (200 to 500 basepairs DNA sequence that has a single occurrence in the human genome and whose location and base sequence are known. Detectable by polymerase chain reaction (PCR), STSs are useful for localizing and orienting the mapping and sequence data reported from many different laboratories and serve as landmarks on the developing physical map of the human genome. Expressed sequence tags (ESTs) are STSs derived from cDNA.
A short DNA sequence with a known chromosomal location that occurs once within the human genome.
short DNA sequence (200-500 bp) that has a single occurrence in the human genome with known location and sequence. STSs can be detected by PCR methods and are useful as landmarks on the genome, to localize and orient sequence data.
A short stretch of DNA whose sequence occurs once in the genome and whose location is known. It serves as a landmark used in the mapping and assembly of a genome.
Short DNA segment that occurs only once in the human genome and whose exact location and order of bases are known. Because each is unique, STSs are helpful for chromosome placement of mapping and sequencing data from many different laboratories. STSs serve as landmarks on the physical map of the human genome.
