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.

Here is what is clear: the average prisoner on death row has spent 13 years there, and his odds of growing old in prison are pretty good. About 3,300 inmates are on death row in the United States.Last year, there were 46 executions.According to a study published in 2004 in the Journal of Empirical Legal Studies, 5 percent of the 5,826 death sentences imposed from 1973 to 1995 were carried out in those years.bout 3,300 inmates are on death row in the United States.
