Darkly stained region in a nucleus is called
WebThis tissue is stained by a method that produces a dark black stain on the myelin. The neuronal cell bodies are the pale, tan structures, and the nucleus can be made out as a slightly lighter region within the cell body. Inside the nucleus is the dark black nucleolus, an organelle where ribosomes are made. WebSolution: A typical nudeosome contains 200 b p of D N A helix. Nudeosomes constitute the repeating unit of a structure in nucleus called chromatin. Chromatin is held over a scaffold of non-histone chromosomal (or N H C) proteins.At some places chromatin is densely packed to form darkly stainined heterochromatin.

Did you know?
WebWhen stained, the nucleus appears darker than the surrounding cytoplasm. The cytoplasm is the region of the cell outside the nucleus. It contains fluid, ribosomes, the cytoskeleton, and, in eukaryotes, other membrane-bound organelles. The minute “power-plants” in the cytoplasm of cells are called mitochondria. WebThis was based initially on the fact that nucleoli appear as dark holes (although a weak signal is present) when cells are stained with intercalating DNA dyes such as 4',6-Diamidine-2'-phenylindole dihydrochloride (DAPI) ( Fig. 11.3A), but the same holds true for the distribution of tagged histones incorporated into nucleosomes (Müller et al., …
WebB. Chromatin – the genetic material inside the nucleus. It consists of 46 strands of DNA that are spread throughout the nucleus. When a cell is preparing to divide, the chromatin will coil itself up into short compact structures called chromosomes. C. Nucleoli – darkly stained regions of the nucleus. The DNA in these areas of the nucleus WebThe semi-fluid internal medium of a cell that dissolves molecules between the nucleus and cell membrane is called: cytoskeleton The internal structures of a cell that maintain its shape and allow it to move are called: hydrophilic, hydrophobic
