fig. 10.4. Creation of a “minimal genome” from the natural genome of a living
microbe. The natural genome of
Mycoplasma genitalium
contains 482 genes. removing
all genes not essential to the microbe's life leaves a minimal genome containing 381
genes absolutely essential to maintain life. The same procedure can generate minimal
genomes from other species of microbes.
fig. 10.5. Transformation of one species into another by genome (DnA)
transplantation. introducing the isolated genome from species 1 into a cell from species
2 containing its own genome produces a cell with two different genomes. When this
cell divides, some of the daughter cells receive genome 1 and others receive genome
2. Daughter cells with donor genome 1 have the appearance and behavior of species 1
cells, as do all of the offspring of these cells.
