Detailed explanation-1: -Organisms composed of cells that contain nuclei are classified as eukaryotes, whereas organisms composed of cells that lack nuclei are classified as prokaryotes. In eukaryotes, DNA is housed within the nucleus, but in prokaryotes, DNA is located directly within the cellular cytoplasm, as there is no nucleus available.

Detailed explanation-2: -What is DNA made of? DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

Detailed explanation-3: -The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.

Detailed explanation-4: -Cytoplasm does not contain genetic materials The cytoplasm is literally the ‘cell substance’ and it is kind of a ‘molecular soup’ of all kinds of different things with various functions. It is not just ‘filler fluid’. But, none of a cells genetic materials are found in the cytoplasm.
