Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.
Are chromosomes chromatin?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. During cell division, the structure of the chromatin and chromosomes are visible under a light microscope, and they change in shape as the DNA is duplicated and separated into two cells. …
Are chromatin and chromosomes made of the same thing?
The main difference between chromatin and chromosome is that chromatin consists of the unravelled condensed structure of DNA for the purpose of packaging into the nucleus whereas chromosome consists of the highest condensed structure of the DNA doublehelix for the proper separation of the genetic material between …
How are chromosomes formed from chromatin?
The cellular DNA is replicated during interphase, resulting in the formation of two copies of each chromosome prior to the beginning of mitosis. As the cell enters mitosis, chromatin condensation leads to the formation of metaphase chromosomes consisting of two identical sister chromatids.
Are chromosomes made of DNA?
Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.
Is chromatin a prokaryote?
Eukaryotic chromosomes are composed of chromatin, and each consists of two complementary strands of DNA coiled tightly around histones. The structure of chromatin is scaffolded, with three distinct levels.
