Answer: Euchromatin
Explanation:The eukaryotic chromosome consists of nucleosomes which are repeated units of chromatin. Nucleosome has the negatively charged DNA forming a complex structure with the histone proteins(8 in number). This structure and packaging of DNA is required for stability of DNA,for accommodating a large DNA molecule in a small space and it also maintains the functions of DNA.
The chromatin structure affects the gene expressions of the particular DNA.
The condensation level of different parts of the DNA also depends on the stages in the cell cycle. The region of the chromatin where active transcription is going on is called euchromatin and the region of chromatin where transcription is inhibited or not taking place is called heterochromatin. Because of the functional variability in these two regions on the chromatin, euchromatin region is less condensed or decondensed.
In interphase when there is more of protein synthesis consequently more gene expression is required most of the euchromatin will be in decondesed state.
This decondensation of euchromatin gives access to various enzymes required for gene expression to move along the DNA.

When the same chromosome is compared between two different cells, regions of heterochromatin and euchromatin are found in different locations between the two cells. Why does the state of chromatin packaging differ along the length of the same chromosome in two different cells?
