Multiple Choice
Which molecule is responsible for bringing amino acids to the ribosome during protein synthesis?
A
rRNA (ribosomal RNA)
B
tRNA (transfer RNA)
C
mRNA (messenger RNA)
D
DNA (deoxyribonucleic acid)
Verified step by step guidance
1
Understand the process of protein synthesis: Protein synthesis occurs in two main stages, transcription and translation. During translation, amino acids are assembled into a polypeptide chain at the ribosome.
Identify the role of each molecule listed: rRNA (ribosomal RNA) forms the structural and functional components of the ribosome, mRNA (messenger RNA) carries the genetic code from DNA to the ribosome, and DNA (deoxyribonucleic acid) stores genetic information but does not directly participate in translation.
Focus on the molecule responsible for transporting amino acids: tRNA (transfer RNA) is the molecule that carries specific amino acids to the ribosome during translation.
Explain how tRNA works: tRNA has an anticodon region that pairs with the codon on the mRNA strand, ensuring the correct amino acid is added to the growing polypeptide chain.
Conclude that tRNA is the molecule responsible for bringing amino acids to the ribosome during protein synthesis, as it directly interacts with both the mRNA and the ribosome to facilitate translation.
