Figure 38-1: Mycobacteriophage genomic features. A. DNA sequence similarity among 14 completely sequenced mycobacteriophage genomes. B. Relationship between %GC content and genome length for all dsDNA phage genomes smaller than 100kbp. Phages are as follows: mycobacteriophages (squares), E. coli and Salmonella phages (small circles), Dairy phages (diamonds) and others (large circles).
