Answer: Alfred Wegener ; Continents
Explanation:
The continental drift theory states that continents of earth have moved over geologic time period relative to each other which appears to have drifted along the ocean bed.
This concept was fully developed and explained by Alfred Wegener in the year 1912 but due to the lack of information about any motive mechanism his theory was rejected.
It is being subsumed by the theory of the tectonic plates by the continents moving because of the movement of the tectonic plates.
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
