While start codons need nearby sequences or initiation factors to start translation, stop codon alone is sufficient to initiate termination.
Termination of protein synthesis depends on release factors that recognize the three stop codons.
When a stop codon (UAG, UAA, or UGA) arrives at the A site, it is recognized and bound by a protein release factor.
The three stop codons are UAA, UAG, and UGA. These codons signal the end of protein translation during protein synthesis. When a stop codon is encountered, release factors bind to the ribosome, causing the newly synthesized protein to detach.
The three stop codon sequences are: UAA, UAG and UGA.
This sequences are not translated to any amino acid. The matching t-RNA molecules don't carry amino acid in their 3' end instead there's a release factor that cause the polypeptide to be released from the tRNA, the tRNA is released from the ribosome, and the two ribosomal subunits separate from the mRNA.

All except three codons provide codes for amino acids These three codons are used as signals?
Of the 64 codons, the three that do not code for amino acids are stop codons.The stop codons are:TAG in DNA (UAG in mRNA)TAA (UAA)TGA (UGA)They signify the end of the gene, i.e. the end of the segment to be transcribed and translated.
At the end of DNA what are the three codons called?
The three codons at the end of a DNA sequence are known as stop codons. They signal the termination of protein synthesis during translation.
What 3 codons do not carry amino acids?
The three codons that do not carry amino acids are UAA, UAG, and UGA. These codons are known as stop codons and signal the end of protein synthesis.
How many start and stop codons are there?
There is only one start codon, which is AUG (codes for methionine), and three stop codons, which are UAA, UAG, and UGA. These codons play essential roles in initiating and terminating protein synthesis during translation.
How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total

At the end of DNA what are the three codons called?
The three codons at the end of a DNA sequence are known as stop codons. They signal the termination of protein synthesis during translation.
Which codons are the stop signals?
There are three such codons known as stop codons, which are UAA, UAG, or UGA.
What codons stop protein synthesis?
The codons that signal the termination of protein synthesis are known as stop codons. In the genetic code, there are three stop codons: UAG, UAA, and UGA. When a ribosome encounters one of these codons during translation, it signals the end of protein synthesis and the release of the completed protein.
What 3 codons do not carry amino acids?
The three codons that do not carry amino acids are UAA, UAG, and UGA. These codons are known as stop codons and signal the end of protein synthesis.
How many start and stop codons are there?
There is only one start codon, which is AUG (codes for methionine), and three stop codons, which are UAA, UAG, and UGA. These codons play essential roles in initiating and terminating protein synthesis during translation.
How many codons are in aaaugcucguaa?
There are four codons in AAA UGC UCG UAA. A codon is a sequence made of three nitrogenous bases. Codons have particular features, making it possible for them to be start codons, stop codons, introns, or exons.
How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
What are the punctuation codons?
Punctuation codons are the three stop codons in the genetic code: UAA, UAG, and UGA. These codons signal the termination of translation during protein synthesis.
What is true about codons?
Codons are sequences of three nucleotides in mRNA that specify a particular amino acid. There are 64 possible codons, including start and stop codons. Codons are central to the process of translation, where they are matched with complementary anticodons on tRNA molecules to assemble proteins.
How many different codons are possible with the four different nucleotides?
There are 64 possible different codons (4 nucleotides in a sequence of 3), including 61 codons that code for amino acids and 3 stop codons.
All except three codons provide codes for amino acids?
B. stop
