CRISPR-Cas System: Next Generation Genome Editing Tool
Abstract: CRISPR-Cas system provides sequence specific adaptive immunity against phages and mobile genetic elements. Resistance is acquired following phage infection or plasmid uptake when short specific sequence is added into CRSIPR array. This complex guides cRNA to target complementary DNA fragments and target its degradation. CRISPR array is then transcribed and processed into cRNA which forms complex with cas protein. The ability of CRISPR-Cas system to induce site specific DNA breaks …

Coordinated Checkpointing Algorithms: A Comparative Analysis
Abstract: In distributed system collection of independent computers appear to the users as a single computer. The property of fault tolerance is that it enables a system to continue operating properly if the failure occurs in the event of some of the components. Minimum process coordinated checkpointing is an appropriate approach to initiate fault tolerance in mobile distributed systems. Checkpoint-based rollback recovery restores the system state to the most recent reliable …
