When a eukaryotic gene is cut out of genomic DNA, geneticists have discovered that enabling the strands to hydrogen bond allows them to hybridize one of the gene's strands to the mRNA for that gene. How can you tell whether this gene undergoes alternative splicing by comparing the mRNAs that result?
