When a genome contains a cluster of genes with related sequences, mispairing between nonallelic loci can cause unequal crossing over. This produces a deletion in one recombinant chromosome and a corresponding duplication in the other.

The K+ that enters hair cells via the mechanically-sensitive cation channels is recycled. In the cochlea, K+ eventually reaches the stria vascularis and is secreted back into the endolymph, completing the cycle

Nonsense mutation in one gene of a transcription unit was found to prevent the expression of subsequent genes in the unit even though both genes had their own ribosome binding sites, an effect called polarity.

Rho-dependent termination sites within a transcription unit are usually masked by translating ribosomes and therefore rho cannot act on downstream RNA polymerases
