Amino acids are transferred to the ribosome by transfer RNA (tRNA) molecules. During translation, tRNAs carrying specific amino acids bind to the ribosome and deliver their amino acids to the growing polypeptide chain through complementary base pairing between the anticodon on the tRNA and the codon on the mRNA. This process ensures the accurate incorporation of the correct amino acid into the growing protein chain.
tRNA molecules (transport RNA's) bring the amino acids to the ribosome for protein synthesis. They link on to the amino acids through an acyl side chain. At the ribosome, the anti codon loop of the tRNA interacts with the codon on the mRNA
The synthesis of a polypeptide chain occurs during translation of protein synthesis. During translation, transfer RNA molecules pick up amino acids in the cytoplasm and insert them into their proper positions in the protein.

What statement best describes the function of tRNA in translation?
tRNA carries specific amino acids to the ribosome during translation. It recognizes the codon on the mRNA through its anticodon and brings the corresponding amino acid to the growing polypeptide chain.
How are tRNA polypeptide and anticodon related?
tRNA is a type of RNA molecule that carries amino acids to the ribosome during protein synthesis. The tRNA has an anticodon sequence that is complementary to the mRNA codon, allowing it to base pair with the mRNA and ensure the correct amino acid is added to the growing polypeptide chain.
What is the purpose of a transfer RNA?
Transfer RNA (tRNA) plays a crucial role in protein synthesis by carrying specific amino acids to the ribosome during translation. Each tRNA molecule has an anticodon region that binds to the corresponding codon on messenger RNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
What element transports and positions amino acids?
The element that transports and positions amino acids is tRNA (transfer RNA). tRNA molecules carry specific amino acids to the ribosome during protein synthesis and ensure that the correct amino acid is added to the growing polypeptide chain according to the sequence of mRNA.
What is the role of tRNA in translation?
Transfer RNA (tRNA) plays a crucial role in translation by bringing amino acids to the ribosome, where they are added to the growing polypeptide chain according to the mRNA sequence. Each tRNA molecule carries a specific amino acid and has an anticodon region that base pairs with the corresponding codon on the mRNA, ensuring accurate translation.
The step of translation in which amino acids are added one at a time to the growing polypeptide is?
The step of translation in which amino acids are added one at a time to the growing polypeptide is called elongation. During elongation, transfer RNA (tRNA) molecules carrying amino acids enter the ribosome and add their amino acids to the growing chain in a sequence determined by the mRNA codons.
How many ribosomes are needed for the production of a polypeptide containing thirty amino acids?
One ribosome is needed to synthesize a polypeptide containing thirty amino acids. The ribosome reads the mRNA and assembles the amino acids into a polypeptide chain according to the codons on the mRNA.
Amino acids are transferred to the ribosome to be incorporated into a growing polypeptide chain by?
transfer RNA (tRNA) molecules. Each tRNA carries a specific amino acid at one end and has a unique three-nucleotide sequence called an anticodon at the other end, which pairs with a complementary codon on the mRNA. This process ensures that the correct amino acids are brought to the ribosome and added to the growing polypeptide chain.
Which molecule directs the synthesis of a polypeptide at a ribosome?
Messenger RNA (mRNA) directs the synthesis of a polypeptide at a ribosome by providing the instructions encoded in its nucleotide sequence for the order in which amino acids should be linked together to form the polypeptide.
What statement best describes the function of tRNA in translation?
tRNA carries specific amino acids to the ribosome during translation. It recognizes the codon on the mRNA through its anticodon and brings the corresponding amino acid to the growing polypeptide chain.
What type of RNA carries amino acids to the ribosome?
Transfer RNA (tRNA) carries amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon that pairs with the codon on the mRNA to ensure the correct amino acid is added to the growing polypeptide chain.
What dictates the corresponding sequence of amino acids in a growing polypeptide chain?
The sequence of amino acids in a growing polypeptide chain is dictated by the sequence of nucleotides in the mRNA template. Each set of three nucleotides, called a codon, corresponds to a specific amino acid, as specified by the genetic code. Transfer RNA molecules bring the correct amino acids to the ribosome based on the codons in the mRNA, allowing the polypeptide chain to be assembled in the correct order.
How are tRNA polypeptide and anticodon related?
tRNA is a type of RNA molecule that carries amino acids to the ribosome during protein synthesis. The tRNA has an anticodon sequence that is complementary to the mRNA codon, allowing it to base pair with the mRNA and ensure the correct amino acid is added to the growing polypeptide chain.
When is the polypeptide (protein) released from the ribosome?
Polypeptides are proteins, just they are short. For example, Insulin is a protein of just 56 amino-acids; it could be considered to be a very large polypeptide.
Which kind of RNA has an anticodon region and carries the amino acids to the ribosome?
Transfer RNA (tRNA) has an anticodon region that base pairs with the codon on mRNA during translation. tRNA also carries specific amino acids to the ribosome according to the genetic code, where they are added to the growing polypeptide chain.
What are ribosome EPA sites?
Ribosome EPA sites are specific locations within a ribosome where tRNAs bind during protein translation. The EPA sites stand for Exit (E), Peptidyl (P), and Aminoacyl (A) sites, each playing a crucial role in the elongation phase of translation by facilitating the addition of amino acids to a growing polypeptide chain.
What is the purpose of a transfer RNA?
Transfer RNA (tRNA) plays a crucial role in protein synthesis by carrying specific amino acids to the ribosome during translation. Each tRNA molecule has an anticodon region that binds to the corresponding codon on messenger RNA, ensuring that the correct amino acid is added to the growing polypeptide chain.
