YOU HAVE TWO LOOK AT BOTH
The process of matching up strata from a lot sites through
the physical, other properties and analysis of chemical. While biostratigraphic
dating a relative dating method that uses the associations of fossils in strata
to analyze each layer's age approximately. C. by matching color from several
sites across distances strata by chemical composition and is the answer.
One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
