Current Research: Identification of Tandem Repeats in DNA sequences
My current research is the study of complex pattern structures associated
with tandem repeats occurring in DNA. The goal is to identify tandem
repeat regions which actually occur in sequence data. My extensive
analysis of GenBank sequence data uncovered challenging tandem repeat
regions described by complex patterns. These sequences motivated my
Tandem repeats exhibit several complex pattern structures. Multi-periodic
tandem repeats (MPTRs) are regions which exhibit more than one periodicity.
Nested tandem repeats are described by tandem repeats nested within tandem
repeats. Variable length tandem repeats (VLTRs) are nested tandem
repeats where the nested repeat has a varying copy number.
I've developed an algorithm for identifying tandem repeats having both
simple and complex pattern structures. The algorithm uses no prior
knowledge of region periodicity or pattern. The analysis uses a
period-independent threshold approach to select potential tandem repeat
regions and sets no artificial upper limit for periodicity.
