1.2 The Nucleus and DNA

All About the Nucleus

Why is the Nucleus so Important?

Summary

The nucleus is responsible for several important things:

  • storage of DNA, which contains the “master set” of instructions for all of the cell's activities

  • control of the cell's production of proteins by copying information from DNA

  • containing the nucleolus, where ribosomes are made.
