WebTo perform analysis on STR markers, the invariant flanking regions surrounding the repeats must be determined. Once the flanking sequences are known then PCR primers can be designed and the repeat region amplified for analysis. ... This hexanucleotide DNA marker has been optimized and performance verified for direct PCR amplification from … WebMay 14, 2024 · Like DNA transposons, retrotransposons generate direct repeats at their new sites of insertion. In fact, it is the presence of these direct repeats that often is the clue that the intervening stretch of DNA arrived there by retrotransposition. Some 50% of the entire human genome consists of retrotransposons. LINEs (Long interspersed elements)
