Chromosomes consists of DNA bound with histone that are present in similar weight or sth else?
Chromosomes are the “packed up form” of DNA with bound protein (togenter called chromatin) which exist in the nucleus as a discrete number for all cells in an animal or plant. In a cell that is not actually dividing (in interphase) the DNA is unravelled and individual chromosomes cannot be seen. The DNA contains the gene sequences that are the basis of gene expression to form proteins. Have a look at Cell Chromatin the associated Chromatin image and a Chromosome table.
