In the conversation between Grant and Wu, they discuss the challenges of DNA analysis and how technology has advanced since the 1960s. Wu explains that while it's no longer necessary to spend years decoding DNA, the sheer size of the DNA molecule makes it impractical to work with the entire strand. Instead, scientists focus on the specific sections that differ between species or contemporary DNA, as only a small percentage of nucleotides vary.

This process of analyzing these unique segments is still complex and time-consuming, emphasizing the intricacies involved in genetic research. The advancements in computer technology have significantly sped up the analysis, reducing what once took years to mere hours. Despite these improvements, the task remains substantial, highlighting the continued effort required in the field of genetics.
