... The "private alleles" technique provides an alternative approach to estimating Nm (Slatkin 1985b); however, this technique requires a sufficient number of private alleles (alleles that occur in only one deme) and reasonably large sample sizes to obtain unbiased estimates. The method is based on the ...

The unknown spectrum did not match up well with that of chalcone because it contained a peak around 270nm that chalcone lacks. The peaks of the unknown at 270nm and 362nm suggest that the unknown is a flav ...

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.
