WebDec 14, 1990 · Current analyses of genes often focus on relatively short stretches of DNA and consider chromatin conformations that incorporate only a few kilobases of DNA. In interphase nuclei, however, orderly transcription and replication can involve highly folded chromosomal domains containing hundreds of kilobases of DNA. WebSep 27, 2024 · Interphase is the stage of the cell cycle that occurs before mitosis and prepares the cell for division. During this phase, the cell grows and DNA is replicated.
