Functionally homologous DNA replication genes in fission and budding yeast.
The cdc18(+) gene of the fission yeast Schizosaccharomyces pombe is involved in the initiation of DNA replication as well as in coupling the S phase to mitosis. In this work, we show that the Saccharomyces cerevisiae CDC6 gene complements cdc18-K46 ts and cdc18 deletion mutant S. pombe strains. The budding yeast gene suppresses both the initiation and the checkpoint defects associated with the ...
متن کاملCharacterisation of 3' end formation of the yeast HIS3 mRNA.
The nucleotide (nt) sequence of the 3' end of the yeast HIS3 mRNA was determined by PCR amplification of the 3' end. Analysis of 28 individual clones revealed that at least 13 distinct polyadenylation sites are present. The sites of polyadenylation are extremely heterogeneous and do not show any obvious similarity other than that they occur after pyrimidine residues in most cases. Most mutants ...
متن کاملSignals sufficient for 3'-end formation of yeast mRNA.
The following three elements were previously shown to be required for 3'-end formation of mRNA in the yeast Saccharomyces cerevisiae: (i) the efficiency element TATATA or related sequences, which function by enhancing the efficiency of downstream positioning elements; (ii) the positioning element AATAAA or related sequences, which position the poly(A) site; and (iii) the actual poly(A) site, wh...
متن کاملGenetic instability in budding and fission yeast—sources and mechanisms
Cells are constantly confronted with endogenous and exogenous factors that affect their genomes. Eons of evolution have allowed the cellular mechanisms responsible for preserving the genome to adjust for achieving contradictory objectives: to maintain the genome unchanged and to acquire mutations that allow adaptation to environmental changes. One evolutionary mechanism that has been refined fo...
متن کاملTiming Robustness in the Budding and Fission Yeast Cell Cycles
Robustness of biological models has emerged as an important principle in systems biology. Many past analyses of Boolean models update all pending changes in signals simultaneously (i.e., synchronously), making it impossible to consider robustness to variations in timing that result from noise and different environmental conditions. We checked previously published mathematical models of the cell...
