Best Answer

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 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 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.


What halts translation in DNA?

Translation in DNA is halted by stop codons, specifically the three codons—UAA, UAG, and UGA—that signal the ribosome to stop adding amino acids to the growing polypeptide chain. When a stop codon is encountered, release factors bind to the ribosome, causing it to release the completed protein and dissociate from the mRNA molecule.


When do human eyes stop growing?

Human eyes typically stop growing in size around the age of three, reaching their adult size. However, the eyes continue to change and develop in terms of vision and function throughout life.


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.

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.


What happens to the growing of polypeptide?

It will either continue growing, or develop into a functional protein.


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 places the amino acid on the growing polypeptide chains?

Ribo


What is added to the polypeptide strand?

Amino acids are added to the growing polypeptide strand during protein synthesis. Ribosomes facilitate the process by reading the mRNA and catalyzing the formation of peptide bonds between the amino acids. This results in the elongation of the polypeptide chain until a stop codon is reached.


How can I stop growing?

Do feet stop growing?

Eventually they do when you reach a certain age where you stop growing.....So YES feet do stop growing! EVENTUALLY!


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.
