Answer:
The answer is E
Explanation:
Work has been done on the functions of RNA over the years involving a group of scientists and their teams.
These scientists include Brenner, Crick, Meselson, as well as Watson.
There were limitations to establishing the functions of RNA, one of which access to more primitive techniques, machines and equipment stands out.
This limited the amount of knowledge scientists had access to about RNA but as time went by , the function of RNA was established to be linked to DNA.
Better technology provided better techniques to determine how much DNA is expressed and how much RNA functions in translating and transcribing the information carried in DNA which in turn, provides a template for the functions of the RNA present in cells.
