Question

Differentiate between Euchromatin and heterochromatin.

Answer 1

The arrangement of the euchromatin can be represented as a widely spread set of beads in a thread where the beads constitute the nucleosome. Heterochromatin helps in the packaging of the same sequences of DNA in all the cells of the same species.

Complete answer:

Euchromatin	Heterochromatin
The staining of euchromatin might not result in heteropycnosis; heteropycnosis is the differential staining of parts of chromosomes.	The staining of heterochromatin can cause heteropycnosis; heteropycnosis is the differential staining of areas of chromosomes.
Euchromatin doesn’t exist in two forms. It only exists as constitutive euchromatin.	The two regular heterochromatin include constitutive heterochromatin and facultative heterochromatin.
The transformation of euchromatin to heterochromatin helps in regulation of gene expression and replication.	Heterochromatin has different functions. Some of these include regulation of genes and reliability in chromosomes.
Few genes like housekeeping genes are always arranged in chromatin conformation as they have to be incessantly replicated and transcribed or demolition of chromosomes by endonucleases.	The tightly packed DNA in heterochromatin stops the chromosomes from various protein factors that might direct to the binding of DNA.

Note: Euchromatin is further lightly packed DNA that is exemplified by less extreme staining and DNA sequences that are transcriptionally dynamic or might become transcriptionally active at some point. Heterochromatin is a firmly packed or condensed DNA that is identified by intense stains when stained with nuclear stains holding transcriptionally dormant sequences.
