Quizplus · Accepted Answer

PCR (Polymerase Chain Reaction) amplifies specific DNA sequences, and agarose gel electrophoresis allows for the visualization of DNA fragments by size. Together, these methods can help determine if the gene lengths are the same across species by amplifying the gene of interest and comparing the sizes of the resulting DNA fragments.
