NEET BIOLOGY

Detailed explanation-1: -The presence of a nucleus is the principal feature that distinguishes eukaryotic from prokaryotic cells. By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center.

Detailed explanation-2: -1: Eukaryotic Nucleus: The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

Detailed explanation-3: -Eukaryotic cells have membrane-bound organelles. The nucleus stores DNA. The endoplasmic reticulum and Golgi body are involved in protein maturation and transport.

Detailed explanation-4: -The nuclear envelope is a membrane similar to the cell membrane around the whole cell. There are pores and spaces for RNA and proteins to pass through while the nuclear envelope keeps all of the chromatin and nucleolus inside.
