"Another measure of the DNA compaction is given by comparing the volume of the DNA to the volume of the capsid. For example, the length of the bacteriophage ? genome is 16µm and it is stored in a 58 nm diameter spherical capsid (primary source). Taking DNA to be a cylinder 2 nm in diameter, the ? genome takes up a volume of roughly 50,000nm^3 which should be compared to 100,000nm^3, the approximate volume available within the capsid. This corresponds to a solution DNA density of about 500 mg/mL." For value of 50nm see BNID 100235 |
