DNA nullomers as a statistical phenomenon
Nullomers are sequences absent from a certain genome. Due to their unexpected occurrence in short sequences, a hypothesis is that they are avoided for evolutionary reasons or because they might have lethal consequences on organisms. However, we present evidence that the occurrence and frequency of nullomers in genomes is expected as a stochastic consequence of uneven base pair combination…
