The nucleic acid part of an organelle is actively synthesized in
The nucleic acid part of an organelle is actively synthesized in
The correct option is B Nucleolus
A. This organelle has two major functions: it stores the cell's hereditary material or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
B. The nucleus of many eukaryotic cells contains a structure called a nucleolus. As the nucleus is the "brain" of the cell, the nucleolus could loosely be thought of as the brain of the nucleus. The nucleolus takes up around 25% of the volume of the nucleus. This structure is made up of proteins and ribonucleic acids (RNA). Its main function is to rewrite ribosomal RNA (rRNA) and combine it with proteins. This results in the formation of incomplete ribosomes. There is an uninterrupted chain between the nucleoplasm and the interior parts of the nucleolus, which occurs through a system of nucleolar passages. These passages allow macromolecules with a molecular weight up to 2,000 kDa to be easily circulated throughout the nucleolus.
C. Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus. Ribosomes on the rough endoplasmic reticulum are called 'membrane-bound' and are responsible for the assembly of many proteins. This process is called translation.
D. The cytoplasm is the gel-like substance in the cell. It contains all the organelles (structures with a specific job in a cell) such as the mitochondria, nucleus, ribosomes. The cytoplasm also serves a purpose for Maintaining cell structure (helps the cell membrane to form a spherical shape and prevent collapsing of the cell).
So, the correct answer is “Nucleolus”.
