Final answer:
The human genome is approximately 652 times larger than the E.coli genome.
Step-by-step explanation:
The human genome is much larger than the E.coli genome. The human genome has three billion base pairs per haploid set of chromosomes, while the size of the E.coli genome is 4.6 million base pairs. This means that the human genome is approximately 652 times larger than the E.coli genome.
