The genetic material of the escherichia coli cell with a diameter of about 1 μm and a length of about 2 μm, consists of a dna molecule with a diameter of 2 nm and a total length of 1.36 mm. (the molecule is actually circular, with a circumference of 1.36 mm.) to be accommodated in a cell that is only a few micrometers long, this large dna molecule is tightly coiled and folded into a nucleoid that occupies a small proportion of the cell's internal volume. calculate the smallest possible volume the dna molecule could fit into, and express it as a percentage of the internal volume of the cylindrical bacterial cell with a diameter of about 1 μm and a length of about 2 μm. recall that v=pr2h for a cylinder.
