What is the primary function of ribosomes in a cell?

Ribosomes are essential cellular structures primarily responsible for synthesizing proteins through a process known as translation. During this process, ribosomes read the sequence of messenger RNA (mRNA) and use that information to assemble amino acids into polypeptides, which then fold into functional proteins. This function is crucial because proteins play a vital role in nearly every cellular process, contributing to the structure, function, and regulation of the body’s tissues and organs. The active engagement of ribosomes in protein synthesis directly makes them pivotal to the overall functioning of cells and organisms. The other options, while important functions within biological systems, do not accurately describe the primary role of ribosomes.
