Difference between chromatin and chromatid
Introduction
In the eukaryotic cell, the genetic material is contained in the cell nucleus in the form of chromosomes. These chromosomes are made up of chromatin and chromatids, the structure and function of which can be confusing to many people.
chromatin
Chromatin is a complex structure of proteins and DNA found in the nucleus of the cell in its interphase state. That is, when the cell is not dividing and the DNA is in a less compact form.
- It is made up of DNA, histones and non-histone proteins.
- It is found in the cell during interphase.
- It is a less compact structure and longer than the chromatid.
chromatid
The chromatid, on the other hand, is a shorter, more compact structure that forms when chromatin condenses during cell division.
- It is a single structure of a DNA helix.
- It is half of a complete chromosome.
- It joins with another chromatid to form the complete chromosome.
Key Differences Between Chromatin and Chromatid
| Feature | chromatin | chromatid |
| Forma | Longer and less compact | Shorter and more compact |
| Composition: | DNA, histones and non-histone proteins | a DNA helix |
| cell state | Interface | Cellular division |
| Amount in the cell | More than one per chromosome | one per chromosome |
Conclusion
In summary, chromatin and chromatid are two different structures that exist in the nucleus of the eukaryotic cell. While chromatin is a complex structure of proteins and DNA found in the cell during interphase, chromatid is a shorter, more compact structure that forms when chromatin condenses during cell division. It is important to understand the difference between these structures as it is crucial in understanding the cellular cycle and the formation of new cells.
