In later chapters, you will learn more about the regulation of gene expression. One way to regulate gene expression is to make changes to the histone proteins to alter how tightly the DNA is coiled and wrapped. The more tightly coiled and wrapped a particular region of DNA is, the less likely it is that the genes in that region will be expressed. Bearing this in mind, how tightly do you think regions of heterochromatin are compacted?

Respuesta :

Answer:

Highly condensed.

Explanation:

The different region of the eukaryotic chromosome are euchromatin region and heterochromatin region. The heterochromatin region is genetically inactive whereas euchromatin region is highly active.

The heterochromatin region is generally present at the periphery of the nucleus. This region is transcriptionally inactive. This is because of the compactness of DNA. DNA is packed very tightly or present in highly condensed form with the histones.

Thus, the answer is highly condensed.
