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 else can I help you with?
Does tRNA have anti-codons?
"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.
The process of translation occurs in the?
The process of translation occurs in the ribosomes of a cell. It involves the decoding of messenger RNA (mRNA) into a specific sequence of amino acids to form a protein. Transfer RNA (tRNA) molecules bring the corresponding amino acids to the ribosome during translation.
What molecule would you find anticodon?
Anticodons are found on transfer RNA (tRNA) molecules. They are specific sequences of three nucleotides that complement the codons on messenger RNA (mRNA) during protein synthesis. The anticodon region of tRNA base-pairs with the corresponding codon on mRNA to ensure accurate translation of genetic information into proteins.
What statement best describes the function of tRNA in translation?
tRNA carries specific amino acids to the ribosome during translation. It recognizes the codon on the mRNA through its anticodon and brings the corresponding amino acid to the growing polypeptide chain.
What is the result of the translation process?
An amino acid chain
What are the base sequence called in tRNA?
They are anticodons
Do anticodons utilize urasil?
Yes, some anticodons contain uracil. In mRNA, uracil pairs with adenine, while in tRNA anticodons, uracil pairs with adenine in the corresponding codon during translation.
Trna has codons or anticodons?
anti-codons for sure!

What are base sequences in tRNA called?
Anticodons
What are the base sequences in trna?
Anticodons
What the difference between mRNA and tRNA?
mRNA is the RNA that carries information during transcription and translation. It has codons, which match up with the anticodons on tRNA. tRNA is the RNA that bonds to amino acids and transfers them to ribosomes, and mRNA.
Which two structures contain codons and anticodons?
Codons are found in mRNA molecules, which are involved in protein synthesis during translation. Anticodons, on the other hand, are found in tRNA molecules, which are responsible for carrying amino acids to the ribosome based on the mRNA codons.
In protein synthesis the anticodons are found on the?
The anticodons are found on tRNA molecules. tRNA molecules bring specific amino acids to the ribosome during protein synthesis. Each tRNA molecule has an anticodon region that is complementary to the codon on mRNA.
Anticodons would be characteristic of?
Anticodons are characteristic of transfer RNA (tRNA) molecules. They are sequences of nucleotides within tRNA that are complementary to codons in messenger RNA (mRNA), allowing tRNA to correctly decode the genetic information in mRNA during protein synthesis.
Are codons and anticodons found in DNA?
Codons are sequences of three nucleotides found in DNA that code for specific amino acids. Anticodons are complementary sequences found in tRNA that recognize and bind to codons during protein synthesis. So, codons are found in DNA, while anticodons are found in tRNA.
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.
