ANATOMY

Detailed explanation-1: -In eukaryotic cells, genomic DNA is compactly stored in the nucleus by wrapping DNA around histone cores. The nuclear envelope (NE), composed of a double lipid bilayer and a structure called the nuclear lamina, encloses chromatin via the interaction between the nuclear lamina and chromatin.

Detailed explanation-2: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA.

Detailed explanation-3: -The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA).

Detailed explanation-4: -Eukaryotic DNA is packed into bundles of chromosomes, each consisting of a linear DNA molecule coiled around basic (alkaline) proteins called histones, which wind the DNA into a more compact form.

Detailed explanation-5: -Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. Enclosing the nucleoplasm is the nuclear envelope, which is made up of two layers of membrane: an outer membrane and an inner membrane.
