| Title |
WT_Asynchronous_23C_Nucleosomes |
| Sample type |
SRA |
| |
|
| Source name |
WT W303
|
| Organism |
Saccharomyces cerevisiae |
| Characteristics |
synchronized: Asynchronous
temperature: 23C
fragmentation: micrococcal nuclease
|
| Growth protocol |
wild-type (W303) and mutant (orc1-161) yeast strains were grown at the permissive temperature (23C) in rich medium for all experiments.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Mononucleosomes were prepared from 1.5 x 10^9 cells that were cross-linked with .1% formaldehyde for 30 minutes and quenched with 125 mM glycine. After cross-linking, the cells were spheroplasted and treated with 80 units of micrococcal nuclease to generate mononucleosome fragments. 50 ng of isolated mononucleosomal DNA fragments were prepared for sequencing using the genomic DNA sample preparation kit (Illumina) according to the manufacturer's instructions.

| Description |
MNase digestion of WT mononucleosomal fragments
|
| Data processing |
Mapview alignment files were generated with the program MAQ, which was fed the raw data in the Illumina fastq format, and a build of the S. cerevisiae S288C from SGD (released 12/16/2005). All of the default options were used, except that the maximum number of allowed mismatches was raised to 3. All further processed data was generated using in-house analysis methods described in the GSE16926_nucleosomes_2009_supp.pdf.
