<span>Multiple mutations in the DNA over several reproductions lead to mutations that give rise to malignancies. Cancer cells reproduce at an accelerated rate and do not die in the same time frame as normal cells, resulting in masses of cells (tumors).</span>
<span>The transmission of information from DNA to RNA is a critical process. We compared RNA sequences from human B cells of 27 individuals to the corresponding DNA sequences from the same individuals and uncovered more than 10,000 exonic sites where the RNA sequences do not match that of the DNA. All 12 possible categories of discordances were observed. </span>
