Table 1. Frequency of spreading of sequence from a single tagged telomere to all other telomeres in K. lactis cells lacking telomerase.

Tagged telomere	No. of clones	No. of clones with spreading of tag (%)
Bcl	195	20 (10)
Long Bcl	78	74 (94)
Long Kpn	40	38 (95)

K. lactis ter1Δ cells initially containing a single telomere tagged with mutant repeats were grown by serial streaking through 75–100 cell divisions on rich-media plates and examined for spreading of the mutant repeats to all other telomeres.
