What regions of a ribosome holds the growing polypeptide?
The P site and the A site of the ribosome hold the growing polypeptide chain during translation. The P site is where the tRNA carrying the growing polypeptide is located, and the A site is where the new tRNA carrying the next amino acid in the sequence enters.
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA corresponds to the linear sequence of amino acids in a polypeptide through the process of translation. Each three-nucleotide codon on the mRNA molecule codes for a specific amino acid, and the sequence of codons determines the order in which amino acids are added to the growing polypeptide chain. This relationship is known as the genetic code.
What is a sequence of 3 n-bases in a row of trna called?
A sequence of 3 bases in a row on tRNA is called an anticodon. The anticodon pairs with the corresponding codon on mRNA during translation to help bring the correct amino acid to the growing polypeptide chain.
How can a mutation in DNA base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
When does a polypeptide stop growing?
A polypeptide stops growing when the ribosome reaches a stop codon on the mRNA template. This triggers the release of the polypeptide chain, along with the ribosome and mRNA, from the protein synthesis machinery.

What sequences of a piece of mRNA is AGUACA what is the matching sequence of the tRNA?
The mRNA sequence AGUACA corresponds to the codons that will be translated into amino acids during protein synthesis. The matching tRNA sequence, which carries the complementary anticodon, would be UCAUGU. Each tRNA molecule pairs with its corresponding mRNA codon to ensure the correct amino acid is added to the growing polypeptide chain.
How can a mutation in DNA base sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
What is on one end of a tRNA stand?
One end of a tRNA molecule features an anticodon, a specific sequence of three nucleotides that base pairs with the corresponding codon on mRNA during protein synthesis. At the opposite end, the tRNA has an attached amino acid, which is determined by the anticodon sequence. This structure enables tRNA to deliver the appropriate amino acid to the growing polypeptide chain during 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.
When does a polypeptide stop growing?
A polypeptide stops growing when the ribosome reaches a stop codon on the mRNA template. This triggers the release of the polypeptide chain, along with the ribosome and mRNA, from the protein synthesis machinery.
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.
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 happens to the growing of polypeptide?
It will either continue growing, or develop into a functional protein.
When does the polypeptide stop growing?
The polypeptide stops growing when it reaches a stop codon on the mRNA during translation. This signals the ribosome to release the polypeptide chain, which then undergoes further processing to become a functional protein.
