How many codons are in an anticodon?
three bases
Explanation: A codon and an anticodon contain per definition three bases: Codons are the sets of 3 bases in mRNA that code for one amino acid. Anticodons are the 3 bases (of tRNA) that bind to the codons of the mRNA.
What is the anticodon corresponding to the codon?
tRNA
Anticodon An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence. An anticodon is found at one end of a transfer RNA (tRNA) molecule.
What is the anticodon for the codon AAG?
UUC
An anticodon is a sequence of 3 bases, and is complementary to the codon for an amino acid. For example, the amino acid lysine has the codon AAG, so the anticodon is UUC.
What does UCA code for?
| Amino acids | Symbols | Codons |
|---|---|---|
| Serine | Ser | AGC, AGU, UCA, UCC, UCG, UCU |
| Threonine | Thr | ACA, ACC, ACG, ACU |
| Valine | Val | GUA, GUC, GUG, GUU |
| Tryptophan | Trp | UGG |
What is anticodon loop?
Of the three stem loops, the anticodon loop contains the three nucleotide base sequence which pairs with the mRNA codon during translation. There are more possible codons (64) than individual tRNAs. While several amino acid types may bind to a tRNA, only one amino acid at a time may bind.
What is the anticodon of Uga?
| Amino Acid | Coding DNA Strand Base Triplets Not Transcribed | Transfer RNA Anticodons Complementary To M-RNA Codons |
|---|---|---|
| stop | TAA, TAG, TGA | AUU, AUC, ACU |
| threonine | ACT, ACC, ACA, ACG | UGA, UGG, UGU, UGC |
| tryptophan | TGG | ACC |
| tyrosine | TAT, TAC | AUA, AUG |
What is the anticodon for UUA?
Solution
| Asparagine (Asn) | Serine (Ser) | |
|---|---|---|
| mRNA codon | AAU or AAC | UC(A, G, U, or C) |
| DNA | TTA or TTG | AG(T, C, A, or G) |
| tRNA anticodon | UUA or UUG | AG(U, C, A, or G) |
What is the anticodon for UGA?
UGA suppression may therefore be a universal feature of the expression of tobravirus genomes. Their amino acid acceptance and nucleotide sequences identify the two UGA-suppressor tRNAs as chloroplast (chl) and cytoplasmic (cyt) tryptophan-specific tRNAs with the anticodon CmCA.
What is the mRNA of TAC?
| Amino Acid | Coding DNA Strand Base Triplets Not Transcribed | Transfer RNA Anticodons Complementary To M-RNA Codons |
|---|---|---|
| threonine | ACT, ACC, ACA, ACG | UGA, UGG, UGU, UGC |
| tryptophan | TGG | ACC |
| tyrosine | TAT, TAC | AUA, AUG |
| valine | GTT, GTC, GTA, GTG | CAA, CAG, CAU, CAC |
What is the relationship between a codon and an anti-codon?
Both codon and Anticodon are specialized to work in pairs in the placement of amino acids and the process of protein synthesis . They are the languages that communicate together and give a byproduct of polypeptides. Specific base pairing initiates the process of codon and anticodon pairing and the stop codon helps in terminating it.
What binds to the complementary codon from tRNA?
A tRNA is an RNA molecule with a three-base anticodon which is complementary to a given mRNA unit of genetic code. Each tRNA is attached to an amino acid, so the ribosome moves down the mRNA transcript, positioning a matching tRNA codon next to each mRNA codon and linking the amino acids before ejecting the tRNA.

How to find the anticodon?
You can find the anti-codon sequence even more quickly by simply writing the DNA sequence , using U for uracil in place of T for thymine. Then split the sequence into the three base anti-codons. You may use the anti-codon sequence to match to the proteins added by each tRNA during translation, creating an amino acid sequence.
Is there only one codon for every amino acid?
Each codon is known to code only one and specific type of amino acid. Some codons together code one amino acid. A table of the various combinations of the 3 nucleotides present that come together to form different types of amino acids is given below.
