That would be the chromatin within the nuclear envelope.

Chromatin
Chromatin is the substance of a chromosome and consists of a complex of DNA and protein in eukaryotic cells. It can be made visible by staining (thus the name which literaly means coloured material). The nucleic acids are generally in the form of double-stranded DNA. The major proteins involved in chromatin are histone proteins. In a eukaryotic cell, nearly all DNA is found compacted in chromatin. DNA is packaged into chromatin both to constrain the size of the molecule and to allow the cell to control expression of the chromatin packaged genes. Changes in chromatin structure are effected mainly by methylation and acylation of the nucleosome proteins. Chromatin structure is also of importance with respect to the DNA replication.
Genetic material (DNA) is also present in the nucleus, the DNA is present as a DNA-protein complex called chromatin. The DNA is present as a number of discrete units known as chromosomes. There are two types of chromatin: euchromatin and heterochromatin. Euchromatin is the least compact form of DNA, and the regions of DNA which constitute euchromatin contain genes which are frequently expressed by the cell.
Chromatid
A chromatid forms one part of a chromosome after it has coalesced for the process of mitosis or meiosis. Each chromosome consists of two exactly identical ("sister") chromatids.
In another Stephen King apocalyptic thriller, technology spells doom for the world as a terrifying Pulse is spread through cell phone signals. The story follows Clay Riddell as he travels to Maine to save his son. Good luck!
