WebAug 22, 2024 · Put simply, DNA interacts with histones, forms chromatins and then a chromosome. It further coils to form 30 nm fiber and a bead-on-string-like structure. Then it becomes chromatid and finally packed on a chromosome. Now let us understand each step precisely. Illustration of the process of DNA packaging from a cell to DNA. WebDNA packaging. Each chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins, and contains a portion of the 6,400,000,000 basepairs (DNA … WebThe DNA in your cells is packaged into 46 chromosomes in the nucleus. As well as being a naturally helical molecule, DNA is supercoiled using enzymes so that it takes up less space. Try holding a piece of string at one end, and twisting the other. As you add twist, the string creates coils of coils; and eventually, coils of coils of coils. bir 2303 for professionals
