Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Remodeling of chromatin is an essential process allowing the establishment of specific genetic programs. The slime mold Physarum polycephalum presents the attractive advantage of natural synchrony of the cell cycle in several million nuclei. Whole-cell extracts prepared at precise stages during the cell cycle were tested for the ability to induce remodeling in erythrocyte nuclei as monitored by microscopy, protamine competition assays, micrococcal nuclease digestions, and release of histone H5. Extracts derived from two specific cell cycle stages caused opposite types of changes in erythrocyte nuclei. An increase in chromatin compaction was imparted by extracts prepared during S-phase while extracts harvested at the end of G2-phase caused increases in nuclear volume, DNA accessibility, and release of linker histone. We also found that late G2 extracts had the ability to alter the DNase I digestion profile of mononucleosomes reconstituted in vitro in a classical nucleosome remodeling assay. The relevance of these finding to the Physarum cell cycle is discussed.
