I think its Only identical twins have the exact same genome.
Well let's take Sedimentary rock for example, The Law of Superposition which measures the average age of Sedimentary rocks using rocks around it. So you would use that rocks below it are older and that Extrusions and Intrusions are younger than the rocks which are stable.
The answer is; electron microscope
This microscope has the highest resolution than the other hence able to view smaller molecules. The reason for its high resolution is because it uses a beam of electrons to view its specimen. A beam of electrons has a shorter wavelength (in order of 1000s of magnitude) compared to visible light. Therefore, this microscope is able to view the structure of DNA and proteins.
