Transcription factors are DNA-binding proteins that attach to specific sites in the DNA to regulate transcription. Transcription is the process of copying DNA to RNA. From there, the RNA can be read to create proteins the cell needs by an enzyme called RNA polymerase. Different cells need different proteins to do their job, so different cells use transcription factors to turn certain genes on or off.  A transcription factor binds to a site in DNA called a promotor. If it turns on the gene, the transcription factor helps recruit RNA polymerase to the DNA to start transcription. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. To increase the visibility and ease of use of open access scientific and scholarly journals PrimeOA Publications top online publishing journals are indexed in different indexing and archiving services.
