Eukaryotic chromosome structure
Eukaryotic chromosome structure refers to the levels of packaging from the raw DNA molecules to the chromosomal structures seen during metaphase in mitosis or meiosis. Chromosomes contain long strands of DNA containing genetic information. Compared to prokaryotic chromosomes, eukaryotic chromosomes are much larger in size and are linear chromosomes. Eukaryotic chromosomes are also stored in the nucleus of the cell, while chromosomes of prokaryotic cells are not stored in a nucleus.
==History==
Some of the first scientists to recognize the structures now known as chromosomes were Schleiden, Virchow, and Bütschli, O. The term was coined by Heinrich Wilhelm Gottfried von Waldeyer-Hartz, referring to the term chromatin, which was introduced by Walther Flemming.
In the 1900s, many scientists concluded the same ideas of heredity that Gregor Mendel had previously. Scientists also discovered plant and animal cells have a central compartment called the nucleus. They soon realized chromosomes were found inside the nucleus and contained different information for many different traits.
