Detailed explanation-1: -In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.
Detailed explanation-2: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA.
Detailed explanation-3: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-4: -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: -Both eukaryotic and prokaryotic cells contain it. Nuclear DNA is the DNA that is found in the nucleus of each eukaryotic organism’s cell. In a prokaryotic cell, the DNA is present in the small region of the cytoplasm known as the nucleoid.
