== Differences between chromatin and chromosome ==
In eukaryotic cells, chromatin and chromosomes are two structures that consist of DNA and proteins and are located in the nucleus.<ref name="ref1" /><ref name="ref2" /> The primary distinction between them relates to their level of condensation and their appearance at different stages of the cell cycle.<ref name="ref3" /> Chromatin is the less condensed form of the genetic material that is present during the non-dividing phase of the cell (interphase), while a chromosome is the highly condensed structure visible during cell division.<ref name="ref4" /><ref name="ref5" />

Chromatin's main function is to package long DNA strands into a more compact form to fit within the cell's nucleus.<ref name="ref1" /> This packaging is achieved by wrapping DNA around proteins called histones, forming units known as nucleosomes. These nucleosomes are linked together, creating a structure often described as "beads on a string".<ref name="ref1" /> This organization not only prevents DNA from tangling but also regulates gene expression, DNA replication, and repair, as the DNA must be unwound to be accessible for these processes.

When a cell prepares to divide, the chromatin undergoes extensive coiling and condensation to form chromosomes.<ref name="ref2" /> This higher-order packaging makes the genetic material manageable, ensuring its accurate segregation into two daughter cells during mitosis or meiosis.<ref name="ref1" /> Each duplicated chromosome that is visible during metaphase consists of two identical sister chromatids joined at a centromere.<ref name="ref4" /> This compact, X-shaped structure is temporary and serves to protect the DNA from damage during cell division.<ref name="ref1" /> After division is complete, the chromosomes uncoil and return to the less condensed chromatin state.<ref name="ref4" />

! Feature !! Chromatin !! Chromosome
|-
| '''Definition'''
| A complex of DNA, RNA, and proteins (primarily histones) that makes up the contents of the nucleus.<ref name="ref1" />
| A highly condensed structure of chromatin, visible during cell division, that carries genetic information.
|-
| '''Structure'''
| Long, thin, uncoiled fibers.<ref name="ref3" /> Its basic unit is the nucleosome.
| Thick, compact, ribbon-like, and highly coiled structure.<ref name="ref3" /> Replicated chromosomes often have a visible X-shape with two sister chromatids.
|-
| '''Condensation'''
| Less condensed, allowing access for transcription and replication.<ref name="ref4" />
| Highly condensed, facilitating segregation during cell division.
|-
| '''Stage in Cell Cycle'''
| Present throughout interphase (the non-dividing stage).<ref name="ref4" /><ref name="ref3" />
| Forms and becomes visible only during cell division (mitosis and meiosis).
|-
| '''Visibility'''
| Not individually visible with a light microscope; appears as a diffuse mass.<ref name="ref4" /><ref name="ref3" />
| Clearly visible with a light microscope, especially during metaphase.
|-
| '''Primary Function'''
| DNA packaging, regulating gene expression, and enabling DNA replication.<ref name="ref1" />
| Ensuring the precise and equal segregation of genetic material to daughter cells during division.
