What do we call a codon that signals the end of a polypeptide chain?
A codon that signals the end of a polypeptide chain is called a stop codon. There are three specific stop codons in the genetic code: UAA, UAG, and UGA. When a ribosome encounters one of these codons during translation, it triggers the termination of protein synthesis.
What do you mean by stop codons?
a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.Three codons UAG,UAA & UGA are the stop codons, which denotes the end of the protien.
The termination codons that serve as stop signals for the protein synthesis is called?
The answer is "Non-sense" codons
What is the termination signal?
The termination signal is a sequence of DNA that signals the end of transcription in prokaryotic organisms. This signal causes RNA polymerase to detach from the DNA template strand, releasing the newly synthesized RNA molecule. In eukaryotic organisms, termination signals are more complex and involve multiple factors.
What is the final step of transcription?
The final step of transcription is the termination of RNA synthesis, where the RNA polymerase enzyme reaches a specific termination sequence in the DNA template. This signals the end of the gene, prompting the RNA polymerase to detach from the DNA and release the newly synthesized RNA molecule. The RNA undergoes further processing, such as capping and polyadenylation, before it is ready for translation.
What amino acid is UAG?
UAG in RNA is amber. In RNA it is a stop codon which is a nucleotide triplet within messenger RNA that signals a termination of translation.
What halts translation?
The termination codon on the mRNA strand stops translation by signaling the ribosome to release the polypeptide chain. This termination codon does not code for any amino acid and instead signals the end of protein synthesis.
Describe the difference between a termination signal and a stop codon?
Termination signal is at the end of the part of the chromosome being transcribed during transcription of mRNA. While in a stop codon, also called termination codon, is a nucleotide triplet within messenger RNA that signals a termination of translation.
What is the protein synthesis termination triplet?
The protein synthesis termination triplet is the stop codon found in mRNA that signals the end of translation. The three stop codons are UAA, UAG, and UGA. When a ribosome encounters a stop codon, it signals the release of the newly synthesized protein.
When does translation end in eukaroytes?
Translation in eukaryotes ends when a stop codon (UAA, UAG, or UGA) is encountered by the ribosome. This signals the termination of protein synthesis and the release of the newly formed polypeptide chain from the ribosome.
What are the three codons that signal the termination of translation?
The three codons that signal the termination of translation are UAA, UAG, and UGA.
What are the three stage of translation?
Initiation, Elongation and, Termination.
What are the punctuation codons?
The three codons UAA (ochre), UAG (amber), and UGA (opal) that do not code for an amino acid but act as signals for the termination of protein synthesis.
What do we call a codon that signals the end of a polypeptide chain?
A codon that signals the end of a polypeptide chain is called a stop codon. There are three specific stop codons in the genetic code: UAA, UAG, and UGA. When a ribosome encounters one of these codons during translation, it triggers the termination of protein synthesis.

a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation.Three codons UAG,UAA & UGA are the stop codons, which denotes the end of the protien.
How does the termination of translation occur?
Termination of translation occurs when a stop codon (UAA, UAG, or UGA) is reached in the mRNA sequence. The ribosome recognizes the stop codon, releasing the polypeptide chain from the ribosome, and translation machinery disassembles. The newly synthesized protein is then free to fold into its functional conformation.
What does UAG condon stand for?
UAG codon stands for "Uracil-Adenine-Guanine" and is one of the three stop codons in the genetic code. It signals the termination of protein synthesis during translation. When the ribosome encounters this codon on the mRNA, it prompts the release of the newly synthesized polypeptide chain, effectively ending the translation process.
