The average thickness of a cell's plasma membrane is approximately 5 to 10 nanometers (nm), an almost impossibly thin dimension that is fundamental to life itself. This delicate yet dynamic boundary governs every aspect of a cell's interaction with its environment, from nutrient uptake to signal transduction.

The total length of DNA in a single human cell stretches for about two meters, an astonishing fact that points to the incredible compactness of our genetic material. Understanding what is the length of each helix within DNA and proteins is essential to grasping how these biological macromolecules are structured and function at a cellular level.
