Diameter of a cell nucleus
WebWhat is the size of a nucleus in nanometers? Cells can vary between 1 micrometer (μm) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). WebApr 5, 2024 · The hydrogen nucleus is the smallest (1.75 * 10-15 m) since it has a single proton. The size of nucleus is of the order of 1.2 * 10-15 m, and the nuclear radii range from 1 - 10 * 10-15 m. Some nucleus is spherical while some are flattened and have deformed shapes. The formula to measure the size of nucleus is: R = R0A1/3.
