Analysis and comparison between the Genome of CRISPR bacteriophages

Abstract

Viruses that infect bacteria are called bacteriophages or shortened as phages. Like all viruses, Phages are absolute parasites, although carry all the information to direct their reproduction in an appropriate host, they have no machinery for generating energy and no ribosomes for making proteins. They are defined as an obligate intracellular bacterial parasite that lacks an independent metabolism. Therefore the CRISPR Bacteriophages has got some unique features for which their genome is a very interesting topic in the field of genetic engineering. Comparison between their genome and investigating their specificity and special characteristics, phage genome comparison shows they are highly specific in their characteristics by their own unique features.
