MICROANATOMY

Detailed explanation-1: -By definition, eucaryotic cells keep their DNA in a separate internal compartment, the nucleus. The DNA is separated from the cytoplasm by the nuclear envelope, which consists of a double layer of membrane. Eucaryotes also have other features that set them apart from procaryotes (Figure 1-31).

Detailed explanation-2: -Eukaryotic chromosomes are found in the cell’s nucleus. The DNA inside the nucleus is organized into chromosomes. At the most basic level, a chromosome is a molecule of DNA that is tightly coiled around proteins called histones. Eukaryotic cells have multiple chromosomes that are linear in shape.

Detailed explanation-3: -A genome is the complete set of genetic information in an organism. It provides all of the information the organism requires to function. In living organisms, the genome is stored in long molecules of DNA called chromosomes.

Detailed explanation-4: -In contrast, in eukaryotes, all of the cell’s chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.
