Very small things on the order of micrometers/smaller that cannot be resolved with a light microscope. Things like viruses, non mitotic DNA, certain bacteria/cells can only be resolved via an electron microscope. Also all these things must be dead first and coated w/ a metal such as gold. Therefore in can't be used to study living organisms. Finally an electron microscope specifically a scanning electron microscope is used to study the surface of larger items w/ very high resolution.
This is from google definitions <span>an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.</span>
the bold is from google. please no report.

Answer:
Explanation:
DNA is a double helical structure. It is a long polymer molecule which has deoxyribose sugar and phosphate backbone. It have four nitrogenous bases which are supported by the phosphate backbone. These are the adenine, guanine, thymine and cytosine.
RNA is a single stranded molecule. It is a polymer with a ribose sugar and phosphate backbone. It also exhibit four nitrogenous bases that are supported by phosphate backbone these are adenine, guanine, cytosine and uracil.
