which is the phenomenon of fitting DNA into dense compact forms (Figure 7). During DNA packaging, long pieces of double-stranded DNA are tightly looped, coiled, and folded so that they fit easily ...

In the nucleus, DNA forms a complex with proteins. This complex is called chromatin and is formed when the DNA wraps around nuclear proteins and then wraps around itself multiple times to condense ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.
