Plasmids 101: Shuttle Vectors

I fell in love with biology because of an image that was honestly quite boring. My Bio 101 professor displayed a codon table — a chart every molecular biologist has seen before, showing how DNA sequences are translated into amino acids. And I was astonished that the molecular language shared by every living thing fit onto a single lecture slide. That shared language is the basis of shuttle vectors, which can function in unrelated host species, even from completely different kingdoms of life....
