Small polydispersed circular DNA (spcDNA) in human cells

... These ®ndings were established by measures of gross chromosomal changes: ampli®cation or recombination (Tlsty et al., 1989; Wright et al., 1990). In fact, gene ampli®cation is used as an indicator of total genomic instability (Tlsty et al., 1989; Tlsty, 1990), as it has been proposed that a common m ...

Helitron (biology)

A helitron is a transposon found in eukaryotes that is thought to replicate by a so-called ""rolling-circle"" mechanism. This category of transposons was discovered by Vladimir Kapitonov and Jerzy Jurka in 2001. The rolling-circle process begins with a break being made at the terminus of a single strand of the helitron DNA. Transposase then sits at this break and at another break where the helitron targets as a migration site. The strand is then displaced from its original location at the site of the break and attached to the target break, forming a circlular heteroduplex. This heteroduplex is then resolved into a flat piece of DNA via replication. During the rolling-circle process, DNA can be replicated beyond the initial helitron sequence, resulting in the flanking regions of DNA being ""captured"" by the helitron as it moves to a new location.
