Chromosomes are made of tightly packed ________ molecules.
Chromosome Structure The DNA structure of a human cell is packed even more tightly. Matter of fact it is 1000 times longer than that of a bacterium cell. Eukaryotic chromosomes contain both DNA and protein tightly packed together to form a substance called chromatin. The protein (histone) allows for the DNA to tightly pack around so that it can ...How are the long DNA molecules found in eukaryotes packed into short chromosomes? DNA is tightly wound around histones,forming nucleosomes. Nucleosomes are tightly coiled and supercoiled to form chromosomes.DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
