"The mechanism in which a release factor recognizes a stop codon is still unknown." Since anticodons are normally on the complementary tRNA. (The tRNA is what 'reads' the codons on the mRNA and ferries in the corresponding amino acid.) During translation stop codons are recognized by "release factors" that bind to the A-site on the ribosomes during translation.

What molecule would you find anticodon?
In the protein/metabolic RNA molecule called transfer RNA. This molecule pichs up individual amino acids in the cytosol and brings them one at a time to the ribosome where the end of the molecule bearing the anticodon docks on the ribosome and adds it's amino acid to the growing polypeptide chain.
Explain the process of translation and tRNA anticodons?
In short, translation is the process of ribosomes reading mRNA and using tRNA to gather the amino acids specified by the mRNA. The tRNA anticodons are complementary to the codons (three nucleotide sequence that represents an amino acid) on mRNA and allow them to be identified by the ribosome. In detail, translation is the second process of making a protein or polypeptide, the first being transcription. During translation, the mRNA leaves the nucleus and moves to the ribosome, usually located on the Rough ER (endoplasmic reticulum) or in the cytoplasm of the cell. The ribosome consists of two subunits, a large and small one. Initiation factors take the mRNA to the small ribosomal subunit, where other initiation factors move the tRNA to the first codon (three nucleotides sequence that represents a particular amino acid.) Then, the large ribosomal subunit attaches to the small subunit, encasing the mRNA and tRNA. The ribosome contains three distinct areas that the tRNA can occupy in the ribosome: the A site, where tRNA enters and receives the existing amino acid chain, the P site, where it comes in contact with the codons on the mRNA, and the E site, where the tRNA prepares to leave the ribosome. The first tRNA enters the P site and always carries N-formylmethionine (fMet), and all subsequent tRNAs enter the A site, then move to the P site then E site. Since tRNA is reusable and can only carry a particular amino acid, its possesses anticodons that represent the amino acid it carries. The first codon on mRNA is always a 'start' codon AUG (amino acid Methionine.) The ribosome moves down the mRNA and 'reads' each mRNA codon and finds the tRNA with the complementary anticodon (for example, if a codon on mRNA was GGG (Glycine), the complementary tRNA would have an anticodon of CCC and would be carrying the amino acid Glycine.) At the end of the mRNA, a stop signal is read by the ribosome and a release enters the A site instead of tRNA, prompting the ribosome to disassemble and be made available for more mRNA. The stop codons (also known as nonsense codons) are UAA, UAG, and UGA; they do not translate into any amino acid.
What part of tRNA should match the codon of the mRNA?
On the tRNA it is called the anticodon.
Does tRNA deliver amino acids to ribosome?
n aminoacyl tRNA synthetase (aaRS) is an enzyme that catalyzes the esterification of a specific amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA (wikipedia)
What statement best describes the function of tRNA in translation?
tRNA carries amino acids to the ribosome.
What are the base sequence called in tRNA?
They are anticodons
Trna has codons or anticodons?
anti-codons for sure!
Anticodons would be characteristic of?
tRNA
What are the base sequences in trna?
Anticodons
What are base sequences in tRNA called?
Anticodons
Are codons and anticodons found in DNA?
I think codons are found on dna. Anticodons are found only on trna.
What kind of RNA is an anticodon a part of?
Transfer RNA (tRNA) carries the anticodon.
What is the puorpose of anticodons?
a codon is a sequence of 3 nucleotides, the tRNA anticodons is the comlementary pairs with its corresponding mRNA codon.
Which two structures contain codons and anticodons?
mRNA tRNA
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons
What is three letter codes of tRNA molecules are known as?
The three-letter codes of tRNA molecules are referred to as anticodons. Anticodons are complementary to the codons in mRNA and enable the tRNA to recognize and bind to the corresponding amino acid during protein synthesis.
What is an anticodon of the transfer RNA for valine?
Anticodons for valine (Val) are: CAA, CAG, CAU, CAC
