Detailed explanation-1: -Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
Detailed explanation-2: -The genetic material is found in every cell. It stores all information about the organism. It varies among different organisms. It controls different functions in the cell, controls the replication of its cell, and the formation of new cells.
Detailed explanation-3: -In addition, most animal cells have a nucleus, a special organelle that stores DNA. The DNA inside the nucleus is usually organized into strings called chromosomes.
Detailed explanation-4: -Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Detailed explanation-5: -The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes. Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA.
