What are the three codonds that would tell the ribosome to stop producing the amino acid chain?
The three codons that signal the ribosome to stop producing the amino acid chain are UAA, UAG, and UGA. These are known as stop codons, and they do not correspond to any amino acids. When the ribosome encounters one of these codons during translation, it triggers the release of the newly synthesized polypeptide chain, effectively terminating protein synthesis.

When is the new Amino acid added to the polypeptide chain?
The new amino acid is added to the polypeptide chain during the elongation phase of translation. This occurs when the ribosome reads the mRNA codon and brings in the corresponding tRNA with the attached amino acid. The amino acid is then added to the growing polypeptide chain through peptide bond formation.
Where in a cell does the attachment of two amino acids molecules take place?
The attachment of two amino acid molecules takes place in the ribosome during the process of translation. The ribosome reads the mRNA sequence and helps to link the amino acids together to form a protein chain. This process is facilitated by transfer RNA (tRNA) molecules carrying specific amino acids to the ribosome.
Which site on the ribosome does the new tRNA bring an amino acid to?
The new tRNA brings an amino acid to the A site on the ribosome. This is where the transfer of the growing polypeptide chain from the tRNA in the P site to the newly arriving amino acid on the tRNA in the A site occurs.
Does translation take place on the ribosome?
Yes, translation takes place on the ribosome. During translation, the ribosome reads the mRNA sequence and assembles amino acids into a polypeptide chain according to the genetic code. This process occurs in the cytoplasm of the cell.
What is the location on ribosome in which the tRNA leaves?
The tRNA leaves the ribosome from the E (exit) site. This is the final step in the translation process, where the tRNA is released from the ribosome after transferring its amino acid to the growing polypeptide chain.
When is the new Amino acid added to the polypeptide chain?
The new amino acid is added to the polypeptide chain during the elongation phase of translation. This occurs when the ribosome reads the mRNA codon and brings in the corresponding tRNA with the attached amino acid.

How are amino acids transfered to the ribosome into a growing polypeptide chain?
The ribosome uses tRNA that matches the current codon (triplet) on the mRNA to append an amino acid to the polypeptide chain. This is done for each triplet on the mRNA, while the ribosome moves towards the 3' end of the mRNA.
What happens to the two amino acids carried by the two tRNA's inside a ribosome?
The two amino acids carried by the two tRNA's inside a ribosome, bind togather with a peptide bond to elongate the protein chain.
Which site on the ribosome does the new tRNA bring an amino acid to?
The new tRNA brings an amino acid to the A site on the ribosome. This is where the transfer of the growing polypeptide chain from the tRNA in the P site to the newly arriving amino acid on the tRNA in the A site occurs.
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.
Adds the correct amino acid to the growing protein chain?
tRNA (transfer RNA) attaches to the mRNA by the codon and anticodon.Each tRNA carries an amino acid that corresponds to the codon on the mRNA. This is how the correct amino acid is added to the chain.
What is the role of tRNA durning translation?
tRNA, or transfer RNA, plays a crucial role in translation by bringing amino acids to the ribosome. Each tRNA molecule carries a specific amino acid and has an anticodon that can base pair with the codon on the mRNA. This allows for the accurate incorporation of amino acids into the growing polypeptide chain.
Does translation take place on the ribosome?
Yes, translation takes place on the ribosome. During translation, the ribosome reads the mRNA sequence and assembles amino acids into a polypeptide chain according to the genetic code. This process occurs in the cytoplasm of the cell.
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 is the location on ribosome in which the tRNA leaves?
The tRNA leaves the ribosome from the E (exit) site. This is the final step in the translation process, where the tRNA is released from the ribosome after transferring its amino acid to the growing polypeptide chain.
Explain how a protein molecule is synthesized from mRNA?
The mRNA brings the necessary code from the DNA to the ribosome. Meanwhile, the tRNA is bringing the anticodon to translate the codon on the mRNA, along with an amino acid which will be connected in a chain by peptide bond to form a protein. Once the tRNA and mRNA aligns themselves into the ribosome, the translation begins and more tRNAs come and go to dump their amino acids. The amino acids are all connected until a large chain is formed. The chain is then modified further to become a functional protein.
