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.It is estimated that humans have almost 22,000 genes distributed on 46 chromosomes. Figure 3.3.4 – DNA Macrostructure: Strands of DNA are wrapped around supporting histones. These proteins are increasingly bundled and condensed into chromatin, which is packed tightly into chromosomes when the cell is ready to divide. DNA Replication1.

Although the DNA helical diameter is only 2 nm, the entire DNA strand in a single cell will stretch roughly 2 meters when completely unwound.[1] The entire DNA strand must fit within the nucleus of a cell, so it must be very tightly packaged to fit. This is accomplished by wrapping the DNA around structural histone proteins, which act as scaffolding for the DNA to be coiled around. The entire ...A single molecule of deoxyribonucleic acid and a protein make up each chromosome (DNA). As bundles of DNA that are tightly wound, chromosomes are found inside the nucleus of practically all of the cells in our body. Histone-like proteins, which give chromosomes their distinctive shape, keep DNA securely wound around them.Bacteria and some single-celled eucaryotes have especially compact genomes; the complete nucleotide sequence of their genomes reveals that the DNA molecules that make up their chromosomes are little more than strings of closely packed genes (Figure 4-13; see also Figure 1-30).
