Detailed explanation-1: -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.
Detailed explanation-2: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.
Detailed explanation-3: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
Detailed explanation-4: -Chromatin-In the nucleus of the cell, the genetic blueprints that carry the directions to cell parts that tells them how to work. Genetic material made of DNA.
