10 Questions
Constitutive heterochromatin can be found in a decondensed state in interphase cells.
False
Facultative heterochromatin is always transcriptionally inactive.
False
Euchromatin is highly condensed and transcriptionally inactive.
False
Chromatin compaction has no influence on the activity of DNA in transcription.
False
Heterochromatin contains highly repeated DNA sequences like those present at centromeres and telomeres.
True
Constitutive heterochromatin is easy to decondense in interphase cells.
False
Genes in a more decondensed state are inaccessible to the transcription machinery.
False
Chromatin structure does not affect gene expression.
False
Constitutive heterochromatin is only present in some cells of an organism.
False
Heterochromatin resembles the chromatin of cells undergoing mitosis in its highly condensed state.
True
