Describe nucleosome supercoiling and its relationship to the radial loop–scaffold model of chromatin packaging.

please fill in the blank When the cell goes from M to GI, the number of nucleosomes on this stretch of DNA should ------, and the width of the chromatin fiber should -------.    Please select one Newly made lamins should ( single peptide = SP), or (nuclear localization = NLS) or (Transit peptide =TP) or ( Transmembrane domain) or ( SP and NLS) or ( SP or TP) or (transcription activating domain) or ( None of these)

Describe constitutive heterochromatin and facultative heterochromatin. Based upon this information, what would you predict would happen during the embryonic development of an organism if some regions of facultative heterochromatin were changed to constitutive regions? Answer in detail.

Compare the import processes of histones which are synthesized in the cytosol but function in the nucleus to package DNA, and the larger DNA polymerase subunits which are also synthesized in the cytosol but function in the nucleus.
