eukarüootide tuumas asuv DNA, histoonide ja mittehistoonsete valkude kompleks, mis on kromosoomide moodustumise aluseks
eukarüootse organismi kromosoomide DNA ja valkude kompleks, mis värvub kromosoomide diferentsiaalvärvimisel eri moodi sõltuvalt kromosoomide kokkupakituse astmest ja DNA-järjestusstruktuurist
Chromatin is a complex of macromolecules found in cells, consisting of DNA, protein, and RNA. The primary functions of chromatin are 1) to package DNA into a more compact, denser shape, 2) to reinforce the DNA macromolecule to allow mitosis, 3) to prevent DNA damage, and 4) to control gene expression and DNA replication. The primary protein components of chromatin are histones that compact the DNA. Chromatin is only found in eukaryotic cells (cells with defined nuclei).
Good to know
Kui kromatiin mitoosi käigus kondenseerub, siis tulevad nähtavale metafaasi kromosoomid.
