Ribosomes:
Ribosomes are the sites of protein synthesis.
All structural and functional proteins (enzymes) coded by the nuclear DNA are synthesized upon cytoplasmic ribosomes. The DNA codes are transcripted into messenger RNA (mRNA) molecules in the chromosomes of the nucleus.
Functions of Ribosomes :
Ribosomes are the main site of protein synthesis. Synthesized proteins is transported by endoplasmic reticulum.
