The assumption that nucleotide changes are generally not transferred to progeny is not used in the molecular clock approach. In fact, the approach relies on the idea that nucleotide changes are passed down through generations, allowing for the estimation of evolutionary divergence times. The other assumptions listed (randomness of nucleotide changes, accumulation in proportion to time, and lack of interference with gene function) are all integral to the molecular clock approach.
