Which two cellular structures have a role in the creation of proteins? A. nucleus and ribosomes B. ribosomes and mitochondria C. nucleus and mitochondria D. mitochondria and nuclear membrane

Nucleus - contains genetic material that is used in the construction of proteins

Ribosomes - use RNA to put together strings of polypeptides, which make up proteins

Mitochondria - synthesize ATP from 6-carbon sugars

Nuclear membrane - surrounds the nucleus and allows some genetic information to pass through

So, Answer A is correct. The nucleus and ribosomes both are involved in creating proteins for the cell.

A. the nucleus and ribosomes
