What are the roles of Cas1, Cas2, and Cas9 proteins in bacterial genome defense?
Homework Answers
Cas1 and Cas2 proteins play a major role in the adaptation phase where segments of bacteriophage DNA are integrated into the CRISPR gene.
Cas9 is an endonuclease that splits the bacteriophage DNA in the interference phase.

The genome of a newly discovered bacterial species (Bacillus sanfranciscus) is sequenced and found to have a circular genome of 8.7 x106base pairs (bp). Open reading frame (ORF) analysis indicated the presence of 7,250 ORFs that encode proteins with an average length of 360 aa. What is the information content of this genome (i.e.– how much information can be encoded in this length of DNA)? Since the genetic code can be considered digital in nature, convert the information content of base pairs...
