Which type of RNA is responsible for transporting the correct amino acid to the ribosome during protein synthesis?
A
Small nuclear RNA (snRNA)
B
Transfer RNA (tRNA)
C
Ribosomal RNA (rRNA)
D
Messenger RNA (mRNA)
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, where protein synthesis occurs.
Recognize that ribosomal RNA (rRNA) is a component of ribosomes, which are the sites of protein synthesis. It helps in the assembly of amino acids into protein chains.
Identify that small nuclear RNA (snRNA) is involved in the processing of pre-messenger RNA (pre-mRNA) in the nucleus, not directly in protein synthesis.
Learn that transfer RNA (tRNA) is responsible for transporting the correct amino acid to the ribosome. It matches the mRNA codon with the appropriate amino acid during translation.
Conclude that the correct type of RNA responsible for transporting amino acids to the ribosome is transfer RNA (tRNA), as it plays a crucial role in decoding the mRNA sequence into a protein.
