WebThe nucleoproteins form two classes, deoxyribonucleoproteins and ribonucleoproteins. Deoxyribonucleoproteins: These largely form the chromosomes; consist primarily of histories and DNA in about equal amounts. However, chromosomes also contain non-histone proteins in smaller amounts.
Nucleolus organizer regions (NORs) are chromosomal regions crucial for the formation of the nucleolus. In humans, the NORs are located on the short arms of the acrocentric chromosomes 13, 14, 15, 21 and 22, the genes RNR1, RNR2, RNR3, RNR4, and RNR5 respectively.
