Question

Draw the nucleus and label its parts. What is the function of the nucleus in a cell?

Answer 1

Hint: The nucleus is known as the cell's director or controller. It is the location where the second process of central dogma takes place. The genetic material is in the nucleus. It also controls growth and cell metabolism.

Complete answer:
Structure of the nucleus:

Functions of the nucleus in a cell are:
-The nucleus provides a genetic transcription site that is isolated from the translation site in the cytoplasm, enabling degrees of gene regulation not available to prokaryotes.
-During the cell cycle, the main purpose of the cell nucleus is to regulate gene expression and mediate DNA replication.
-It regulates an organism's genetic features.
-Protein synthesis, cell division, development, and differentiation are also the responsibility of the organelle.

Additional Information: -The genes in the form of long and thin DNA (deoxyribonucleic acid) chains, referred to as chromatin, are stored as inherited material.
-Protein and RNA (ribonucleic acid) storage in the nucleolus takes place.
The nucleus is a transcription site where messenger RNA (mRNA) is produced for the synthesis of proteins.
-Chromatins are organized into chromosomes in the nucleus during cell division.
-Ribosome processing (protein factories) occurs in the nucleolus.

Note: The nucleus is an organelle that is double membrane-bound. Two membranes, an outer membrane, and an inner membrane form the nuclear envelope. The apertures known as nuclear pores perforate the nuclear membrane. Nuclear membranes surround the nucleus cytoplasm, known as the nucleoplasm. DNA is present in the form of chromatin in the nucleoplasm. The chromatin condenses and thickens into chromosomes as the cell prepares to divide. A spherical body known as a nucleolus is present inside the nucleus, and is closely associated with the nucleolar organizer area of two or more chromosomes of the collection.
