<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">full chromosome set</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for genome that I've seen before include "is the making of you" , "Complete set of individual's chromosomes" , "Full chromosome set" , "Cocktail, borer" , "The full DNA sequence of an organism" .)
