Find out the correct sentence

Options

A. Enzymes packed in lysosomes are made through RER (Rough Endoplasmic Reticulum)
B. Rough endoplasmic reticulum and smooth endoplasmic reticulum produce lipid and protein respectively
C. Endoplasmic reticulum is related with the destruction of plasma membrane
D. Nucleoid is present inside the nucleoplasm of eukaryotic nucleus

Answer

A

Explanation

The undefined nuclear region is the cytoplasm of prokaryotic cells is called nucleoid. The prokaryotic cells consist of a single chromosome, which is direct content of the cytoplasm i.e., there is no nuclear membrane in a eukaryotic cell, the nuclear envelope separates the nucleus from the cytoplasm. The nuclear envelope contains many pores (the nuclear pores) and encloses the liquid ground substance, the nucleoplasm. Within nucleoplasm two types of nuclear structures are embedded-the nucleolus and chromain material. The nucleous may be one or more in number and is not bounded by any membrane. It is rich in protein and RNA (Ribonucleic Acid) molecules and acts as the site for ribosome formation, hence are also known as factory of ribosomes.
