BIOMOLECULES AND ENZYMES

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: -In eukaryotic cells, most DNA is located in the cell nucleus (though some DNA is also contained in other organelles, such as in the mitochondria and the chloroplast in plants).

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: -In eukaryotic cells, genomic DNA is compactly stored in the nucleus by wrapping DNA around histone cores. The nuclear envelope (NE), composed of a double lipid bilayer and a structure called the nuclear lamina, encloses chromatin via the interaction between the nuclear lamina and chromatin.

Detailed explanation-5: -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.
