Answer:
Ribosomes
Step-by-step explanation:
Ribosomes are organelles with the main purpose of protein synthesis in cells, both in eukaryotes and prokaryotes.
Ribosomes create proteins through translation of mRNA, and the linking of amino acids.
These linked amino acids are the proteins, which can also develop into more complex types of protein structures, such as tertiary and quaternary structures.
So, the correct answer is Ribosomes.
