Telomere formation in yeast	1989		.txt	text/plain	698	44	51	In two other families of viral GKS/Tcontaining proteins serine is encoded almost exclusively by UCN, with AGY occurring only once (see table) . An alternative mechanism involves the generation of a new serine codon next to the functionally important one (yielding a GKSS sequence with the two serines encoded by codons of different series) followed by deletion of the original codon. SIR-We recently demonstrated that dur-, ing formation of new telomeres in the yeast Saccharomyces cerevisiae, telomeric sequences are often transferred between DNA termini'. In a recent News and Views article', however, Szostak suggested that the telomere resolution reaction ' (the cleavage between two blocks of telomeric sequences that are oriented as a head-tohead inverted repeat'') can provide an alternative explanation for our data, a possibility that can be addressed definitively by DNA sequencing. Because the resolution reaction is excluded unequivocally by DNA sequence data , telomere-telomere recombination remains the only reasonable explanation for the transfer of telomeric sequences that we have observed.	./cache/cord-354990-2hx7f6ny.txt	./txt/cord-354990-2hx7f6ny.txt
