Phage lambda is essentially the "Hello World" of molecular biology. The fact that a "viral micro-manager" like PreS remained hidden in such a heavily sequenced and scrutinized organism is a great reminder of how much "dark matter" there is in the non-coding regions of viral genomes.
We often think of viral infection as a blunt-force destruction of the host, but this shows it's much more of a delicate, timed choreography. Upregulating the host's DnaN via RNA folding rather than just killing the host immediately is a clever survival strategy that we could potentially co-opt for more stable bioreactors.

We will. My RSS reader is showing me so many articles about researchers understanding that dark matter which is essential to synthetic biotechnology. For one thing it is not enough to put some gene into an organism or even to get that gene expressed, we have to get it expressed strongly and to do that we have to understand how these regulation networks work.
