When the ribosome encounters the codon UGA during translation, it recognizes it as a stop codon. This signals the termination of protein synthesis, leading to the release of the newly synthesized polypeptide chain from the ribosome. Release factors bind to the ribosome, facilitating the disassembly of the ribosomal complex and the release of the mRNA. As a result, translation ends, and the ribosome is free to initiate translation of another mRNA.

What ends translation in DNA?
a stop codon or anti-codon (same thing)
What is the function of a stop condon?
A stop codon, such as UAA, UAG, or UGA, signals the termination of protein synthesis during translation. When a ribosome reaches a stop codon, it recognizes the signal and releases the completed protein from the ribosome.
Do stop codon have an amino acid?
A stop codon (UGA, UAA, UAG) only codes for a stop. No amino acid results from a stop codon.
A stop codon on an mRNA molecule does not code for any?
A stop codon on an mRNA molecule signals the ribosome to stop translating the mRNA sequence into a protein. It does not code for any amino acid and instead marks the end of protein synthesis. The three stop codons are UAA, UAG, and UGA.
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.

What will happen if the ribosome reads uaa uag or uga?
If you are asking this question to cheat at school shame on you. But I don't care I don't know you, I'm not your parent or teacher. It will read "STOP". actually, this answer is correct. When the ribosome reads uaa, uag, or uga, these sequences are known as stop codons. It will read stop. Also, no tRNA can bind to a stop codon... there are no tRNAs with anticodons complementary to the termination codons, so no tRNA enters the A site of the ribosome. Release factors are induced. RF1 to either UAA or UAG, RF2 to either UGA or UAA. RF3 forms a complex with GTP (energy source) and binds to the ribosome. These release factors promote cleave of the tRNA in the P site. GTP is hydrolyzed (reduced) to GDP. The tRNA is released from the P site, mRNA is released from the ribosome, and the ribosome leaves. -zdrum
What code tells a cell to stop making a protein?
The code for a cell to stop making a protein is a stop codon in the mRNA sequence. Proteins are synthesized by the ribosome until it encounters a stop codon (e.g., UAA, UAG, UGA), which signals the end of translation, leading to the release of the protein and dissociation of the ribosome from the mRNA.
What is non sense codon?
A nonsense codon, also known as a stop codon, is a three-nucleotide sequence in mRNA that signals the termination of translation. When a ribosome encounters a stop codon, protein synthesis stops, and the incomplete polypeptide chain is released. There are three stop codons: UAG, UAA, and UGA.
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 is the function of a stop condon?
A stop codon, such as UAA, UAG, or UGA, signals the termination of protein synthesis during translation. When a ribosome reaches a stop codon, it recognizes the signal and releases the completed protein from the ribosome.
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.
How does the ribosome know how to stop making a protein?
It reaches one of the 3 possible stop codons on the mRNA: UAA, UGA, or UAG. These codons do not code for any amino acid, but instead cause the polypeptide release factor to cleave the newly made protein from the last tRNA. (ed. spelling - I mixed got my words up :)
Do stop codon have an amino acid?
A stop codon (UGA, UAA, UAG) only codes for a stop. No amino acid results from a stop codon.
Where do you find a anticodon?
Codon is found on the messenger RNA(m RNA).During translation, the codons on the m RNA are read by the ribosome and amino acid corresponding to the codon is added. when ribosome encounters a stop codon (UAG,UGA and UAA) translation terminates.
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.
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.
