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.

The additional cost of confining an inmate to death row, as compared to the maximum security prisons where those sentenced to life without possibility of parole ordinarily serve their sentences, is $90,000 per year per inmate.he cost of a system in which the number of death-eligible crimes was significantly narrowed would be $130 million per year. The cost of a system which imposes a maximum penalty of lifetime incarceration instead of the death penalty would be $11.5 million per year. Read the report.
