The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.6 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.2 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00058 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.345 SNIP: 0.46 CiteScore™:: 2.5 H-Index: 67

Краткое описание

Although nature’s design of the DNA double helix is ingenious for the storage of information, this design creates topological problems for the processes that occur on the DNA. Cellular processes, such as transcription, replication, chromosomal segregation, and chromosomal condensation, are all complicated by the double helix. The problem is compounded in cells since the DNA is in chromatin. Topoisomerases relax positive and negative superhelical turns in DNA, and thereby topoisomerases have long been recognized as key components of the DNA replication and chromosome segregation and condensation machinery. A role for topoisomerases in the transcription process has also been noted in living cells, but only recently has such a role been recapitulated in the test tube for transcription reactions. New data are discussed that demonstrate that for in vitro transcription reactions, topoisomerases are dispensable when the template is naked DNA, but when the template is reconstituted into chromatin, topoisomerases are required for transcription to proceed efficiently.
