Which type of RNA is primarily responsible for carrying amino acids to the ribosome during protein synthesis?
A
Ribosomal RNA (rRNA)
B
Small nuclear RNA (snRNA)
C
Transfer RNA (tRNA)
D
Messenger RNA (mRNA)
Verified step by step guidance1
Understand the process of protein synthesis, which involves transcription and translation. During translation, amino acids are assembled into a polypeptide chain at the ribosome.
Learn the roles of different types of RNA: Messenger RNA (mRNA) carries the genetic code from DNA to the ribosome, Ribosomal RNA (rRNA) forms the structural and functional components of the ribosome, and Small nuclear RNA (snRNA) is involved in RNA splicing.
Focus on Transfer RNA (tRNA), which is specifically responsible for carrying amino acids to the ribosome. Each tRNA molecule has an anticodon that pairs with the codon on the mRNA and a corresponding amino acid attached to it.
Visualize the process: tRNA molecules bring amino acids to the ribosome, where the ribosome facilitates the formation of peptide bonds between amino acids, creating a polypeptide chain.
Conclude that Transfer RNA (tRNA) is the type of RNA primarily responsible for carrying amino acids to the ribosome during protein synthesis.
