How are eukaryotic chromosomes organized
WebA chromosome consists of DNA packed into thread-like structures which carries our genes, in the nucleus of the cell. Carl Wilhelm von Nägeli first observed chromosomes in plant cells in 1842. Chromosome number is a species-specific character i.e. it differs in number from species to species. Web5 de dez. de 2024 · In eukaryotes, chromosomes consist of a single molecule of DNA associated with many copies of 5 kinds of histones. Histones are proteins rich in lysine and arginine residues and thus positively-charged. For this reason they bind tightly to the …
