Difference Between Chromatin and Chromosomes
The difference between chromatin and chromosomes are as follows:
| Characteristics | Chromatin | Chromosome |
|---|---|---|
| Definition | It is made up of DNA, RNA and special proteins. These proteins are called histones. | A highly compact form of DNA ound wrapped around histone proteins. |
| Presence | It is present throughout the cell cycle. | It is clearly visible and found during cell division as highly condensed structures. |
| Visibility | Chromatin is visualized through an Electron microscope. | A Chromosome is visualized through a Light microscope. |
| Appearance | It is long,thin and threadlike and is usually extended | It is compact, thick, and rod shaped. It is found during cell division. |
| Pairs | It is unpaired. | It exists in pairs. |
| Functions | It helps in gene regulation and gene expression. |
Chromosomes help in the segregation of the gene pool and also store genetic information. |
| Observable | It can be seen in the Interphase stage of the cell cycle . | It is seen in the M-phase or nuclear division. |
| DNA packaging | DNA is packed loosely, allowing Transcription. | DNA is tightly packed, preventing Transcription. |
Difference Between Chromatin And Chromosomes
Chromatin and Chromosomes are two forms of DNA found in different stages of the human body’s cells. DNA is wrapped around histone proteins which results in the formation of a nucleosome. Multiple nucleosomes join together to form chromatin. It is the least condensed form of DNA.
A chromosome, on the other hand, is the most condensed structure of the DNA double helix found inside the nucleus. The DNA in chromosomes is coiled around nuclear proteins and histones, allowing the DNA to be condensed.
