What else can I help you with?
What ends translation in DNA?
a stop codon or anti-codon (same thing)
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
Is "aug" a stop codon in genetic code?
No, "aug" is not a stop codon in the genetic code. It is actually the start codon that signals the beginning of protein synthesis.
Which process stops when a ribosome reaches a stop codon?
When a ribsome reaches a stop codon, the translation process stops and a protein is released.
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.
What is the function to stop a codon?
the stop codon uaa, uag, or uga triggers the ending of the transcription process
What does the stop codon do in the process of protein synthesis?
The stop codon signals the end of protein synthesis by instructing the ribosome to stop adding amino acids to the growing protein chain.
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.
UAG is a stop codon. What might happen if the uracil in this codon was changed to cytosine?
The new codon would code for glutamine. Translation would continue until the ribosome encountered another stop codon or ran out of messenger RNA to translate.ExplanationUAG is an RNA codon. If the uracil (U) in the codon were changed to cytosine (C), the codon would be CAG, which codes for the amino acid glutamine.
A point mutation that changes a codon specifying an amino acid into a stop codon is called a?
nonsense mutation
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.
Why is UAG codon called amber codon?
The UAG codon is a special kind of codon called a stop codon. There are three types of stop codons: amber, ochre, and opal. UAG is an mRNA codon that is specific for the amber stop codon. The amber codon was named after Harris Bernstein, then a Caltech graduate student, whose last name means "amber" in German.
