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.

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.alifornia spends an additional $ 184 million on the death penalty per year because of the additional costs of capital trials, enhanced security on death row, and legal representation.
