Mitochondria establish MCSs with many other organelles, including ER, lysosomes, peroxisomes, the plasma membrane, the Golgi, endosomes, and even lipid droplets.

Pathogenicity islands are a characteristic feature of pathogenic bacteria genomes.These are large regions (10 to 200 kb) that are present in the genomes of pathogenic species but absent from the genomes of nonpathogenic variants of the same or related species.

Pathogenicity islands GC content often differs from that of the rest of the genome, and it is likely that these regions are spread among bacteria by a process of horizontal transfer.

The sum of the number of unique genes and the number of gene families is an estimate of the number of types of genes.

The minimum size of the proteome can be estimatedfrom the number of types of genes.
