Question

Quizplus · Accepted Answer

Ribosomes are composed of both ribosomal RNA (rRNA) and proteins. The subunits of ribosomes are made up of these components, and they come together during protein synthesis to read RNA and build new proteins. Neither mRNA nor DNA are components of ribosomes. tRNA is involved in protein synthesis, but it is not part of the ribosome structure. DNA is the genetic material that codes for RNA and ultimately leads to protein synthesis, but it is not a direct component of the ribosome itself.
