Question

What is the role of a ribosome in protein production?

A. It is the site where amino acids join to tRNA molecules.
B. It is the site where mRNA codons and tRNA anticodons meet.
C. It is the site where a protein strand is folded into its correct shape.
D. It is the site where proteins are packaged and sent where they are needed.

Answer 1

Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
