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.

Times Topic: Capital Punishment. According to the organization, keeping inmates on death row in Florida costs taxpayers $51 million a year more than holding them for life without parole. North Carolina has put 43 people to death since 1976 at $2.16 million per execution.The eventual cost to taxpayers in Maryland for pursuing capital cases between 1978 and 1999 is estimated to be $186 million for five executions.orth Carolina has put 43 people to death since 1976 at $2.16 million per execution.
