WebBookmarking (also " gene bookmarking " or " mitotic bookmarking ") refers to a potential mechanism of transmission of gene expression programs through cell division. During mitosis, gene transcription is silenced and most transcription factors are removed from chromatin. [1] [2] The term bookmarking compares transcription to reading from a book.
