Why is DNA & not RNA is the genetic material in majority of organisms?
Even though they have several differences, a bacterium and a human cell will both contain DNA. With respect to evolution, what does this fact suggest?
The RNA World Hypothesis suggests that the earliest forms of life used RNA as a genome instead of DNA. Why then do we not see organisms alive today with RNA genomes?
