As a subfamily of Argonaute proteins, Piwi is poorly understood compared with Ago subfamily until recent discovery of Piwi protein interacting with piRNA. We did a large scale screening of insect genomes to identify piwi-like genes.Full or partial cDNA sequences were obtained by EST elongation and GENSCAN.IWI domain is of 300 aa in the C-terminal region and structurally similar to RNaseH catalytic domain, which performs a crucial role in slicer activity [6] , [7] and [8] . In animals, Argonaute protein family can be divided into two classes: Ago subfamily and Piwi subfamily.
The AFP recently examined the time an inmate spends on death row between sentencing and execution and questioned if inmates are being punished twice with long-term imprisonment and execution. They found an average inmate spends 13 years on death row, with some spending 30 years or more.he AFP recently examined the time an inmate spends on death row between sentencing and execution and questioned if inmates are being punished twice with long-term imprisonment and execution.

Hearings can last from a few hours to multiple days.â The judge estimated that he and his staff spend 40 to 60 hours per month on some aspect of the death penalty. DâAurora noted that recent cases took an average of 21 years between sentencing and execution date. The cost likely is millions per case,â he noted. âLife sentences without parole would serve us much better, but we are fixated on a process that drains government resources, he concluded. (J. D'Aurora,  Death-penalty cases waste a lot of taxpayers' money , Columbus Dispatch, Aug. 8, 2012).
