Question

Give the functions of the nucleus.

Answer 1

Hint: Nucleus is a membrane-bounded organelle which is found in eukaryotic organisms with membrane bounded and in prokaryotic organisms it is without cell membrane. Nucleus contains the genome of the cell.

Complete answer:
All living organisms have a genome which helps in developmental and maintenance of the cell. Genome is responsible for the protein production and provides all mechanical support to cells and helps in all over development of the multicellular organisms.

Nucleus is the cell organelle which helps in providing sites for the genetic transcription and provides essentials for the translation. So, we can say that, nucleus is that organelle that helps in the performing central dogma of life.

Functions of the nucleus are as follows:
> Cell compartmentalization: Cell nucleus helps in providing specific sites for the specific processes like metabolism, respiration, etc.

> It helps in protein synthesis and reproduction of the cell, which is involved in cell repair, cell replacement and production of new individuals.

> Nucleus provides the site for transcription which leads to the formation of mRNA and this mRNA is sent to cytoplasm for the protein production in ribosomes and tRNA brings the amino acids which are the monomers of the proteins and enzymes.

> Nucleus helps in the controlled growth of the individual with the help of gene expression and transformation of the information from one generation to next generation.

These are the main functions of the cell nucleus.

Note: Nucleus is a Latin word which means “seed”. Thus, the nucleus acts as the seed of the cell. Every metabolic or catabolic process, cytoskeletal arrangement, control and coordination is due to the presence of the nucleus of the cell. Human red blood cells are the cells which do not contain nucleus because they carry oxygen and they don’t want to utilize that oxygen for their own cellular processes so RBCs are enucleated cells.
