The siRNA sequence is modified to introduce a short loop between the two strands. The resulting transcript is a short hairpin RNA (shRNA), which can be processed into a functional siRNA by Dicer in its usual fashion..
HPNA is a network automation system for managing network devices. It is a web based system with a database backend that stores information about managed devices and can log into those devices to run diagnostic and/or configuration changing commands.It uses snmp, tftp, telnet, ssh and other protocols to manage devices.PNA will know to substitute these strings with data for the current device when a task is executed. So the perl command `my $ip = '$tc_device_ip$';` will become something like `my $ip = '10.187.12.34';` when the script is executed by HPNA.
