Light microscopes have a lower resolution because the refracted light waves spread out which make the image a bit blurred. Also, light microscopes can’t magnify as well as election microscopes. To observe internal structures with a light microscope, you usually need to use dyes. Hope this helped!
I believe it is Wegener's theory did not explain how the continents could move.
<h2>Answer and Explanation</h2>
DNA is called deoxyribonucleic acid. DNA is different in all plants and animals but according to the chemical structure, it is the same as double helix strand that is separated from each other. In a person body, all the DNA are the same but they are different if the cells, tissues, and organs are different. There are some mammals have slightly similar DNA that is humans have 99.6% same DNA as the chimpanzees.
DNA replication begins when something called Helicase (an enzyme) unwinds the helix structure of the DNA. It does this so that Primase can then come along and set down an RNA primer.
