General model for duplication of heterochromatin during cell division Microscopy of heterochromatic versus euchromatic nuclei ().. Heterochromatin has been associated with several functions, from gene regulation to the protection of chromosome integrity; [13] some of these roles can be attributed to the dense packing of DNA, which makes it less accessible to protein factors that usually bind ...
The isoforms 1 and 3 of human NPM1 are B23.1 and B23.2 respectively in rat. [7] The isoform 1 is localized to the nucleolus [ 8 ] as is reported for rat B23.1 [ 9 ] [ 10 ] whereas the isoform 3 (B23.2) is nucleoplasmic or cytoplasmic in localization and is expressed at relatively lower levels as compared to isoform 1 in normal rat tissues [ 11 ...

The nuclear lamina consists of two components, lamins and nuclear lamin-associated membrane proteins. The lamins are type V intermediate filaments which can be categorized as either A-type (lamin A, C) or B-type (lamin B 1, B 2) according to homology of their DNA sequences, biochemical properties and cellular localization during the cell cycle.
Nucleoplasm is quite similar to the cytoplasm, with the main difference being that nucleoplasm is found inside the nucleus while the cytoplasm is located inside the cell, outside of the nucleus. Their ionic compositions are nearly identical due to the ion pumps and permeability of the nuclear envelope, however, the proteins in these two fluids ...
Euchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription. Euchromatin stands in contrast to heterochromatin , which is tightly packed and less accessible for transcription. 92% of the human genome is euchromatic.
The eukaryotic genome is organized into a compact chromatin structure that allows only regulated access to DNA. The chromatin structure can be globally "open" and more transcriptionally permissive, or globally "condensed" and transcriptionally inactive. The former (euchromatin) is lightly packed and rich in genes under active transcription.
