Chromosomes are located in the nucleolus
WebIn most eukaryotes, ribosomal DNA consists of tandemly repeated arrays of four or five genes located at the nucleolus organizer region (NOR) of one or more chromosomes. The number of rDNA copies per genome varies enormously among eukaryotes, with the multiplicity of these genes generated primarily through unequal crossing-over/sister … WebNucleoli are made of proteins, DNA and RNA, and form around specific chromosomal regions called nucleolar organizing regions. Malfunction of nucleoli can be the cause of several human conditions called …
