Which list correctly ranks structures by size, from largest to smallest? prokaryotic cell, eukaryotic cell, virus, gene eukaryotic cell, gene, virus, prokaryotic cell eukaryotic cell, prokaryotic cell, virus, gene virus, gene, prokaryotic cell, eukaryotic cell?

The structure when arranged according to size from largest to smallest is as listed below:

1. Eukaryotic cell (size varies from 10,000-100,000 nanometer)

2. Prokaryotic cell (size varies from 200-10,000 nanometer)

3. Virus (size ranging between 50-200 nanometer)

4. Gene - it is very small in size and calculated in kb.
