Chromosome: Justify- euchromatin represents genetically active parts of chromosomes.

Chromosomes' Genetically Active Sections Are Represented by Euchromatin
During interphase, the loosely packed, faintly pigmented area of chromatin that is less compacted is known as euchromatin. In transcription and gene expression, it is essential. Euchromatin is regarded as the chromosome's genetically active region for the reasons listed below:

Genes that are actively transcribing are found in euchromatin, which makes it simple for transcription factors and RNA polymerase to access the DNA sequence.

Less Condensed Structure: The flexible nucleosome arrangement in euchromatin increases the DNA's accessibility to cellular processes, which promotes the creation of RNA.

Gene-rich regions of the genome are linked to euchromatic regions, which frequently have a higher GC content.

Euchromatin stays decondensed throughout interphase, enabling continued gene expression for cellular processes and growth. This is why it is present in the interphase nucleus.

Euchromatin has an active part in cellular activities, including differentiation, growth, and response to stimuli, because it contains genes that are often expressed.

In conclusion, euchromatin is the chromosome's genetically active region because of its open structure, which enables gene transcription and guarantees the healthy operation and control of cellular processes.
