Junk DNA - repetitive sequences
Eukaryote and also human DNA contains large portion of noncoding sequences. As for the coding DNA, the noncoding DNA may be unique or in more identical or similar copies. DNA sequences with high copy numbers are then called repetitive sequences. If the copies of a sequence motif lie adjacent to each other in a block, or an array, we are speaking about tandem repeats, the repetitive sequences di...
متن کاملDNA Fingerprinting Based on Repetitive Sequences of Iranian Indigenous Lactobacilli Species by (GTG)5- REP-PCR
Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...
متن کاملAligning sequences with repetitive motifs
Pairwise sequence alignment is among the most intensively studied problems in computational biology. We present a method for alignment of two sequences containing repetitive motifs. This is motivated by biological studies of proteins with zinc finger domain, an important group of regulatory proteins. Due to their evolutionary history, sequences of these proteins contain a variable number of dif...
متن کاملShort repetitive sequences in green algal mitochondrial genomes: potential roles in mitochondrial genome evolution.
Current data on green algal mitochondrial genomes suggest an unexpected dichotomy within the group with respect to genome structure, organization, and sequence affiliations. The present study suggests that there is a correlation between this dichotomy on one hand and the differences in the abundance, base composition, and distribution of short repetitive sequences we observed among green algal ...
متن کاملTransposon-Derived and Satellite-Derived Repetitive Sequences Play Distinct Functional Roles in Mammalian Intron Size Expansion
BACKGROUND Repetitive sequences (RSs) are redundant, complex at times, and often lineage-specific, representing significant "building" materials for genes and genomes. According to their origins, sequence characteristics, and ways of propagation, repetitive sequences are divided into transposable elements (TEs) and satellite sequences (SSs) as well as related subfamilies and subgroups hierarchi...
