Which structures are contained in the nucleus and direct all activities of the cell including growth and reproduction?
A
chromosomes
B
ribosomes
C
lisosomes
D
ice cream cones
Explanation: 

Detailed explanation-1: -It is engirdled by a structure referred to as the nuclear envelope. The cell’s chromosomes are also confined within it. DNA is present in the Chromosomes, and they provide the genetic information required for the creation of different cell components in addition to the reproduction of life.

Detailed explanation-2: -In the nucleus, the genetic information is organized into strands of DNA called chromosomes.

Detailed explanation-3: -The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

Detailed explanation-4: -The nucleus is composed of various structures namely nuclear envelope, nucleoplasm or nucleus sap nuclear matrix, chromatin and nucleolus. The nuclear membrane forms an envelope like structure around the nuclear contents and is commonly known as a nuclear envelope.

Detailed explanation-5: -The nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell’s chromosomes and is the place where almost all DNA replication and RNA synthesis occurs. The nucleus is spheroid in shape and separated from the cytoplasm by a membrane called the nuclear envelope.
