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.

In California, home to the nation's biggest death row population at 667, it costs an extra $90,000 per inmate to imprison someone sentenced to death â an additional expense that totals more than $63.3 million annually, according to a 2008 study by the state's Commission on the Fair Administration of Justice.e commuted the sentences of all 167 death row convicts, most to life imprisonment without parole. His moratorium is still in effect. Across the country, the number of prisoners exonerated and released from death row is more than 130, with thousands of appeals clogging the courts.
