The trajectory from autosomes to sex chromosomes may start with the emergence of a sex-determining gene with one allele that determines male individuals and the other female individuals. A two-loci model was suggested byCharlesworth et al. (2005)in which mutation in one gene on the proto-X ch...
A new centromeric satellite repeats may arise from DNA autosomal pair can then be chosen to become a new pair of transposons (Kapitonov and Jurka, 1999). There are also sex chromosomes and the cyclic process can continue. The similarities between the pogo-like superfamily of DNA persistence of...

Transposons – jumping genes, mobile genetic elements – composed of a gene coding for a special enzyme and two short flanking segments of DNA called inverted repeats Transposition • Transpositions duplicate genes by inserting copies of DNA segments into new positions in the genome • Result ...
cholerae strains revealed a high rate (62%) of isolates with dysfunctional quorum sensing systems [19]. One example is the prototype strain N16961 that contains a natural frame shift mutation in hapR [20]. It has been shown that V. cholerae strains containing a natural frame shift mutation ...
nc, noncoding; TE, transposons. F, scatter plot of the ratio of all newly identified known and putative RNAs that had at least 10 mappable reads in either normal or PiwiL4 knockdown MDA-MB-231 cells. Red dashed lines correspond to log2 value 1, −1. To search for piRNAs, we ...
Hybrid dysgenesis, a syndrome of sterility and increased mutation in crosses between different strains of the same species, was first shown in Drosophila melanogaster to be driven by P elements that are inherited paternally, but not maternally [1–4]. Activation of this DNA transposon subsequently ...
Leukemia patients bearing the t(4;11)(q21;q23) translocations can be divided into two subgroups: those expressing both reciprocal fusion genes, and those that have only the MLL-AF4 fusion gene. Moreover, a recent study has demonstrated that patients expr
