    Nükleozom

    Moleküler Biyoloji Kavramı

    Yazeka

    Arama sonuçlarına dayanarak oluşturuldu

    Nükleozom, DNA'nın histon proteinleri etrafında sarılmasıyla oluşan temel kromatin birimidir. Ökaryotik hücrelerde DNA'nın çekirdeğe sığmasını sağlayan yapısal ve fonksiyonel bir birimdir.123

    Yapısı, sekiz histon proteininden oluşan bir çekirdek ve yaklaşık 147 baz çifti DNA'dan oluşur. Histon kuyrukları, DNA paketlemesini düzenleyerek gen ekspresyonunu etkiler.135

    Nükleozomlar, DNA'nın sıkıştırılmasında kritik rol oynar ve hücre döngüsüne göre dinamik olarak açılıp kapanabilir. Bu yapı, genetik materyalin düzenlenmesinde epigenetik mekanizmalarla da ilişkilidir.345
