MY GENOME'S BIGGER THAN YOURS
View larger version | Mimivirus startled the world with a genome of nearly 1.2 million DNA base pairs, larger than the genomes of bacteria such as rickettsia. The E. coli-infecting T4 phage has a mere 168,903 base pairs, while E. coli itself has more than 4 million. The DNA in a human mitochondrion (one of a cell's energy factories) contains 16,569 base pairs.
