Quizplus · Accepted Answer

The transposon mutagenesis procedure shown in the figure demonstrates that many genes in Mycoplasma genitalium are not essential for life. This is evidenced by the fact that only 133 out of 482 genes analyzed were found to be essential. The remaining genes could be mutated without causing cell death, indicating that they are not essential.
