DNA in the nucleus is packed into chromatin using proteins.Mitosis requires that the cell's chromatin be further packed into specific structures that are called chromosome which from a unique karyotype for each species.During mitosis the parent cell DNA is separated such that each daughter cell rec...
(1998). The nuclear basket of the nuclear pore complex is part of a higher-order filamentous network that is related to chromatin. J. Struct. Biol. 124, 51-58.Arlucea J, Andrade R, Alonso R, Arechaga J (1998) The nuclear basket of the nuclear pore complex is part of a higher-...
The analysis of testes after silver nitrate staining showed polyploid nuclei with three large and three smaller nucleolar bodies. Early prophase cells had an intensely stained nucleolar body located close to the chromatin and another less evident body located away from the chromatin. The nucleolar ...
Hint:Chromosomes are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contain...
Liquid–liquid phase separation (LLPS) is an important mechanism that helps explain the membraneless compartmentalization of the nucleus. Because chromatin compaction and LLPS are collective phenomena, linking their modulation to the physicochemical features of nucleosomes is challenging. Here, we develop...
Prokaryotic cells lack a nucleus, their nuclear material is found free-floating in the cell cytoplasm in the nucleoid region. Answer and Explanation: In simple terms, the condensed form of DNA is called chromosomes. While the non-condensed form of DNA is called chromatin. Part (a) ...
Chromatin in which of the following states is the most euchromatic? A、in a Barr body B、in the centromere C、in a transcribed gene during G1 phase D、in a silenced gene during M phase E、in a sperm nucleus
aDuring apoptosis, the nucleus becomes shrunken and pyknotic as a result of DNA degradation. The terminal stage of apoptosis is characterized by chromatin condensation along the nuclear margin that also coincides with DNA cleavage into small fragments 由于脱氧核糖核酸退化,在apoptosis期间,中坚力量变得...

mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit within a cell's nucleus. Condensed chromatin fibers form chromosomes...
