Why is Nucleus important for cell ?
Answers
The cell nucleus is a double membrane‐bound organelle that contains the genetic information of the cell packaged in the form of chromatin. The nucleus is a characteristic feature of most eukaryotic cells.
The nucleus is considered to be one of the most important structures of eukaryotic cells as it serves the function of information storage, retrieval and duplication of genetic information. It is a double membrane‐bound organelle that harbours the genetic material in the form of chromatin. It consists of a dynamic mix of nonmembranous subcompartments of varying functional capacity. The specific features of a cell nucleus, especially in terms of the nature and distribution of the subnuclear compartments and the positioning of the chromosomes, depend upon their differentiated state in the organism. The key functions of the cell nucleus include deoxyribonucleic acid replication and further to control gene expression during the cell cycle. Transcription and further post‐transcriptional processing of pre‐messenger ribonucleic acids (mRNAs) occur inside the nucleus and the mature mRNAs are transported into the cytoplasm where the translational events occur. Thus, nucleus provides functional compartmentalisation inside the cell allowing higher levels of gene regulation.
