NEET BIOLOGY

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). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

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.
