In addition to the core histones, which other histone protein is found in most eukaryotic cells and how is it called?
Nucleosomes are organized into a more compact structure. How is this structure called?
To fit within a cell nucleus, what needs the 30-nm fiber needs to do?
What is a protein that one of the mechanisms that result into loop formation needs, named?
What are proteins that are needed for a second mechanism to form a loop formation?
Where is each chromosome located in the cell nucleus?
There is some variability in the compaction level of chromosomes during interphase. What are two terms to describe the compaction level?
- Euchromatin: less compacted regions, usually able of gene transcription.
What is constitutive heterochromatin?
What does constitutive heterochromatin contain and where is it mostly found?
- It is mostly found in telomers and centromers.
What is facultative heterochromatin?
