[i] Total number of colonies found on different spreads of the same transformation mixture per 5 μg of vector.
[ii] Number of correct phenotype: Ade+ Ura−(A); Ade+ Trp− (B); and His+Trp− (C). Number tested: Number of colonies transferred manually or by replica plating to a plate selecting for the targeted YAC arm; upon loss of the original YAC arm, colonies become Ura− (A) or Trp− (B and C).
[iii] 16%–38% of the colonies were red; these were not analyzed further.
