The nucleus contains most of the cell’s DNA. DNA
molecules in a cell contain a code that is the inherited
information, or genes. The role of the genes is to determine
the proteins that a cell can make.

The nucleolus is mainly made up of RNA. RNA is involved in
protein synthesis. mRNA reads DNA and carries the message
to the ribosomes where the proteins are synthesised. tRNA
brings the amino acids to the ribosomes to be joined into
protein chains.

The endoplasmic reticulum (ER) is a series of membranous
channels that store and transport materials. They also
provide a surface on which chemical reactions occur.

The ribosomes are the site of protein synthesis. They can
be free in the cytoplasm or attached to the surface of the
endoplasmic reticulum (ER), making it rough ER.
