Transposons are segments of DNA that can move around to different positions in the genome of a single cell. In the process, they may cause mutations and increase (or decrease) the amount of DNA in the genome of the cell, and if the cell is the precursor of a gamete, in the genomes of any descendants.

The innovation with PCR is in having two primers flanking the target sequence. If you were to set up a reaction with one primer, you could make one DNA copy at a time. But with two primers, copy numbers grow exponentially with each cycle.If the clipped sequence is uniquely aligned to the flanking sequences, xTea annotates the full-length TE as the source TE of the insertion. xTea also applies a breakpoint refinement step by using ...The Cre/lox system is a well-established research tool, especially in the field of mouse transgenics.

Here, we present Flanker, a Python package which performs alignment-free clustering of gene flanking sequences in a consistent format, allowing investigation of MGEs ... In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites. The terms are constructed upon the phrase "flanking/flanked by LoxP". Recombination between LoxP sites is catalysed by Cre recombinase. Floxing a gene allows it to be deleted (knocked out), translocated or inverted in a ...
STRs are inherited just like any gene or segment of DNA. Every individual has two alleles per STR, one inherited from each parent. However, many different alleles are often present within a population. If the inherited alleles for a given STR in an individual are identical (i.e., contain the same number of repeat units), the individual is ...The 5′ flanking region is a region of DNA that is adjacent to the 5′ end of the gene. The 5′ flanking region contains the promoter, and may contain enhancers or other protein binding sites. It is the region of DNA that is not transcribed into RNA.The sequence contains the upstream flank, the STR sequence, and the downstream flank in forward direction, or as reverse complimentary if the strand was specified as reverse in the configuration file.
