Identification of RNA Molecules in Ribosomes

1. Understanding the Context: Ribosomes are complex molecular machines that synthesize proteins by translating messenger RNA (mRNA). They are composed of ribosomal RNA (rRNA) and proteins.

2. RNA Molecules in Ribosomes:

   • mRNA (Messenger RNA): Carries the genetic information from DNA to the ribosome.
   • tRNA (Transfer RNA): Brings amino acids to the ribosome during protein synthesis.
   • rRNA (Ribosomal RNA): The primary component of ribosomes; it catalyzes protein synthesis and maintains the structure of the ribosome.
   • siRNA (Small interfering RNA): Involved in gene silencing; not a component of ribosomes.
   • snRNA (Small nuclear RNA): Plays roles in splicing RNA; not part of ribosomes.

3. Correct Answer: The types of RNA that make up ribosomes are rRNA (ribosomal RNA).

Final Answer

rRNA turns out to be the key component of ribosomes alongside proteins.
