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.

Arizona (9), and Texas (8) accounted for 53% of those. sentenced to death in 2010. Twelve states executed 46 inmates during 2010, 6 fewer. inmates than in 2009. The inmates executed in 2010. had been under sentence of death an average of 14. years and 10 months, which was 9 months longer than. those executed in 2009. Of the 7,879 people under sentence of death between. 1977 and 2010, 16% had been executed, 6% died by. causes other than execution, and 39% received other.
