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.

With 11 executions spread over 27 years, on a per execution basis, California and federal taxpayers have paid more than $250 million for each execution. It costs approximately $90,000 more a year to house an inmate on death row, than in the general prison population or $57.5 million annually.The Attorney General devotes about 15% of his budget, or $11 million annually to death penalty cases.xecuting all of the people currently on death row, or waiting for them to die there of other causes, will cost California an estimated $4 billion more than if they had been sentenced to die in prison of disease, injury, or old age; California death penalty trials have cost as much as $10.9 million.
