Structure/function correlations

The cell nucleus is a remarkable organelle because it forms the package for our genes and their controlling factors. It functions to:

  • Store genes on chromosomes 
  • Organize genes into chromosomes to allow cell division.
  • Transport regulatory factors & gene products via nuclear pores 
  • Produce messages ( messenger Ribonucleic acid or mRNA) that code for proteins 
  • Produce ribosomes in the nucleolus 
  • Organize the uncoiling of DNA to replicate  key genes

The purpose of this presentation will be to show how the nucleus is structured to perform these functions. As you study the presentation, consult your text,
