Controlled vocabulary for /rpt_type qualifier
The original site; Controlled vocabulary for /rpt_type qualifier 2015.11.11 version.
This page contains the current definition, format and controlled vocabularly for repeat type qualifier.
Definition: organization of repeated sequence
Value format: tandem, inverted, flanking, terminal, direct, dispersed, and other
Comment: the values are case-insensitive, i.e. both "INVERTED" and "inverted" are valid;
Definitions of the values:
- a repeat that consists of two or more adjacent copies of a region whose length is greater than one in the same orientation;
- a repeat pair occurring in reverse orientation to one another on the same molecule;
- a repeat lying outside the sequence for which it has functional significance (eg. transposon insertion target sites);
- a repeat at the ends of and within the sequence for which it has functional significance other than long terminal repeat;
- a repeat where the same sequence is repeated in the same direction;
- a repeat that is located at dispersed sites in the genome;
- a repeat that is disrupted by the insertion of another element;
- a sequence directly repeated at both ends of a defined sequence, of the sort typically found in retroviruses (replaces LTR Feature Key);
- a polymeric tract, such as poly(dA), within a non LTR retrotransposon;
- a repeat region located between the X element and the telomere or adjacent Y' element;
- a repeat region located adjacent to telomeric repeats or X element combinatorial repeats, either as a single copy or tandem repeat of two to four copies;
- a repeat region found within the telomere;
- a repeat region found within the modular centromere;
- a repeat exhibiting important attributes that cannot be described by other values.
