NEET BIOLOGY

Detailed explanation-1: -Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.

Detailed explanation-2: -Nucleus. Known as the cell’s “command center, ” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Detailed explanation-3: -DNA in the nucleus directs protein synthesis in the cytoplasm. A gene is the portion of a DNA molecule that controls the synthesis of one specific protein molecule. Messenger RNA carries the genetic information from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.

Detailed explanation-4: -Nucleus is the internal spherical structure of the cell containing the genetic material. It is bound by a nuclear membrane and it controls the activity of all the other organelles of the cell. This is why the nucleus acts as the director or the control centre of the cell.

Detailed explanation-5: -Chromatin-In the nucleus of the cell, the genetic blueprints that carry the directions to cell parts that tells them how to work. Genetic material made of DNA.
