What is the complementary sequence of tRNA Anticodons?
What is its corresponding tRNA anticodon? Explanation: An anticodon is the three-base sequence, paired with a specific amino acid, that a tRNA molecule brings to the corresponding codon of the mRNA during translation. The anticodon sequence is complementary to the mRNA, using base pairs in the anti-parallel direction.
What is the complementary tRNA sequence?
Complementary bases are: adenine (A) and thymine (T), and cytosine (C) and guanine (G). So if one strand of DNA reads A-C-G-C-T-A, then the complementary strand is T-G-C-G-A-T. Each tRNA has a set of three bases on it known as an anti-codon. The anti-codon matches complementary bases in the mRNA sequence.
What is the complementary tRNA anticodon for the mRNA codon?
At one end, the tRNA has an anticodon of 3′-UAC-5′, and it binds to a codon in an mRNA that has a sequence of 5′-AUG-3′ through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.
What are the matching tRNA Anticodons?
Each anticodon on tRNA matches up with a codon on the mRNA. In this way, amino acids are assembled in the correct order dictated by the mRNA code. The ability of tRNA to match codons with appropriate amino acids is codon recognition.
What three amino acids does the complementary mRNA Strand code for?
Answer: Only two amino acids are coded for by the mRNA strand and they are tryptophan and glycine. Explanation: The complementary mRNA strand is UGGCAGUGA. UGG codes for tryptophan, CAG codes for glycine while UGA does not code for any amino acid hence, it’s a stop codon.
What is a tRNA Anticodon?
Anticodon An anticodon is found at one end of a transfer RNA (tRNA) molecule. During protein synthesis, each time an amino acid is added to the growing protein, a tRNA forms base pairs with its complementary sequence on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein.
What is the tRNA Anticodon for UUA?
| Amino Acid | Coding DNA Strand Base Triplets Not Transcribed | Transfer RNA Anticodons Complementary To M-RNA Codons |
|---|---|---|
| asparagine | AAT, AAC | UUA, UUG |
| aspartic acid | GAT, GAC | CUA, CUG |
| cysteine | TGT, TGC | ACA, ACG |
| glutamic acid | GAA, GAG | CUU, CUC |
How are mRNA codons related to anticodons in tRNAs?
Each three-nucleotide “codon” in the mRNA is matched with an “anticodon” containing the complementary bases. The “transfer RNAs” or “tRNAs” that string proteins together each have one anticodon that corresponds to one mRNA codon, and one amino acid attached.
How are anticodons added to the protein chain?
When the correct tRNA finds the mRNA, its amino acid is added to the growing protein chain. Enzymes catalyze the bonding of amino acids together as tRNA anticodons bind to the correct mRNA codon. When the tRNA’s amino acid has been added to the protein chain, the tRNA leaves to pick up a new amino acid to bring to a new mRNA.
Which is tRNA attaches to a serine amino acid?
The anticodon is a perfect complementary match to a codon. So, if the codon for serine is AGC, then the anticodon for serine is UCG. The tRNA that contains the anticodon UCG will also be the tRNA that attaches to a serine amino acid. Okay, maybe I should back up for just a second.
How did I get the anticodon for the codon AGC?
So, if the codon for serine is AGC, then the anticodon for serine is UCG. The tRNA that contains the anticodon UCG will also be the tRNA that attaches to a serine amino acid. Okay, maybe I should back up for just a second. How did I get the anticodon for the codon AGC?
