Which type of RNA is primarily responsible for carrying amino acids to the ribosome during protein synthesis?
A
Messenger RNA (mRNA)
B
Small nuclear RNA (snRNA)
C
Transfer RNA (tRNA)
D
Ribosomal RNA (rRNA)
Verified step by step guidance1
Understand the role of each type of RNA in protein synthesis: Messenger RNA (mRNA) carries the genetic code from DNA to the ribosome, Ribosomal RNA (rRNA) forms the structural and functional components of the ribosome, Small nuclear RNA (snRNA) is involved in RNA splicing, and Transfer RNA (tRNA) carries amino acids to the ribosome.
Recall the process of translation, where the ribosome synthesizes proteins by reading the mRNA sequence and assembling amino acids in the correct order.
Identify the specific function of tRNA: It acts as an adapter molecule that matches the codons on the mRNA with the corresponding amino acids using its anticodon region.
Recognize that tRNA is essential for delivering amino acids to the ribosome during translation, ensuring the correct sequence of amino acids in the growing polypeptide chain.
Conclude that the type of RNA primarily responsible for carrying amino acids to the ribosome during protein synthesis is Transfer RNA (tRNA).
