A human chromosome 13-specific cosmid library has been screened with oligonucleotides containing tri- and tetranucleotide repeats with motifs: GACA, GACT, CAC, TCC. 20 cosmid clones were identified and their physical location on chromosome 13 was determined using fluorescence in situ hybridisation. Over 80% of the cosmids were detected using tetranucleotide repeats of which 50% were GACT, but these were distributed along the length of the chromosome. Clones from the 13q12-->q14 and 13q32-->q34 regions were apparently overrepresented and 10% of cosmids were localised to the short arm of the chromosome. These simple tandem repeats will be an important addition to the genetic mapping strategy for human chromosome 13.

UI MeSH Term Description Entries
D009838 Oligodeoxyribonucleotides A group of deoxyribonucleotides (up to 12) in which the phosphate residues of each deoxyribonucleotide act as bridges in forming diester linkages between the deoxyribose moieties. Oligodeoxynucleotide,Oligodeoxyribonucleotide,Oligodeoxynucleotides
D012091 Repetitive Sequences, Nucleic Acid Sequences of DNA or RNA that occur in multiple copies. There are several types: INTERSPERSED REPETITIVE SEQUENCES are copies of transposable elements (DNA TRANSPOSABLE ELEMENTS or RETROELEMENTS) dispersed throughout the genome. TERMINAL REPEAT SEQUENCES flank both ends of another sequence, for example, the long terminal repeats (LTRs) on RETROVIRUSES. Variations may be direct repeats, those occurring in the same direction, or inverted repeats, those opposite to each other in direction. TANDEM REPEAT SEQUENCES are copies which lie adjacent to each other, direct or inverted (INVERTED REPEAT SEQUENCES).

D015723 Gene Library A large collection of DNA fragments cloned (CLONING, MOLECULAR) from a given organism, tissue, organ, or cell type. It may contain complete genomic sequences (GENOMIC LIBRARY) or complementary DNA sequences, the latter being formed from messenger RNA and lacking intron sequences.

D017404 In Situ Hybridization, Fluorescence A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei.
