Multiple Choice

Which of the following correctly describes the roles of tRNA and rRNA in protein synthesis?

tRNA is involved in transcription, while rRNA is involved in translation.

tRNA and rRNA both carry genetic information from DNA to the ribosome.

tRNA forms the core of the ribosome's structure, while rRNA carries amino acids to the ribosome.

tRNA carries amino acids to the ribosome, while rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

Verified step by step guidance

Understand the roles of tRNA and rRNA in protein synthesis. tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during translation, matching them to the codons on the mRNA strand. rRNA (ribosomal RNA) is a structural component of the ribosome and plays a catalytic role in forming peptide bonds between amino acids.

Identify the process of translation. Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids in a polypeptide chain. This occurs in the ribosome, where rRNA is a key structural and functional component.

Clarify the role of tRNA in translation. tRNA molecules have an anticodon region that pairs with the corresponding codon on the mRNA strand. Each tRNA is linked to a specific amino acid, which it delivers to the growing polypeptide chain at the ribosome.

Clarify the role of rRNA in translation. rRNA molecules form the core of the ribosome's structure and are involved in catalyzing the formation of peptide bonds between amino acids, facilitating the assembly of the polypeptide chain.

Review the correct description: tRNA carries amino acids to the ribosome, while rRNA forms the core of the ribosome's structure and catalyzes protein synthesis. This description accurately reflects the distinct roles of tRNA and rRNA in the process of translation.
