Even the crossing over cannot take place. During interphase, euchromatin is in hydrated and lightly coiled condition, hence lightly coloured; In most organisms, constitutive heterochromatin occurs around the chromosome centromere and near telomeres.

Which of the following are examples of heterochromatin in a mammalian chromosome? B) the binding of transcription factors to a promoter. Which of the following are examples of heterochromatin? Euchromatin and heterochromatin are the two structural forms of dna in the genome, which are found in the nucleus.

There are many kinds of heterochromatin. They are so compactly organized that they are inaccessible to the protein involved in gene expression. During interphase, euchromatin is in hydrated and lightly coiled condition, hence lightly coloured; A third way is to erase heterochromatin by exposure to inhibitors (for example, the hdac inhibitor trichostatin a) and determine whether mutant cells recover heterochromatin.

In heterochromatin formation, which of the following are responsible for recruiting histone deacetylases and histone methyltransferases to a nucleation site? Euchromatin and heterochromatin are the two structural forms of dna in the genome, which are found in the nucleus.

Examples of this type of heterochromatin occur in the centromeric and telomeric regions. Heterochromatin maintains the structural integrity of the genome and allows the regulation of gene expression. Around 90% of the human genome consists of euchromatin.

Barr body, centromeres, telomeres, etc are examples of various heterochromatin. Around 90% of the human genome consists of euchromatin. This region often contains genetic. Even the crossing over cannot take place. For example, dna methylation involves the addition of a methyl group, which prevents the expression of certain genes, rather than altering the sequences.
