Q

6 Functions of the nucleus

A

-Stores genes in chromosomes
-Organize the genes into chromosomes which allow the cell to divide
-Transports gene products through nuclear pores
-mRNA is sent into the cytoplasm
-Produces ribosomes
-Organizes the uncoiling of DNA to reveal certain genes at certain times
