How does a ribosome match an amino to a codon on the mRNA it is reading even though amino acids cannot directally base pair with nucleuic acids?
Ribosomes match amino acids to codons on mRNA through the use of transfer RNA (tRNA) molecules. Each tRNA has an anticodon region that is complementary to a specific codon on the mRNA and carries a specific amino acid. When the ribosome facilitates the binding of the tRNA's anticodon to the corresponding mRNA codon, it ensures that the correct amino acid is added to the growing polypeptide chain. This process allows for the accurate translation of genetic information into protein.
What does tRNA anticodon bind with?
In normal conditions C always Paris with G and A with U in mRNA so in this CAG the anticoodon wil be GUC
Suppose one of the bases on the mRNA was changed would the same tRNA molecule still attach to the strand?
If a base on the mRNA is changed, it may affect the binding of the corresponding tRNA molecule as the anti-codon of the tRNA needs to match the codon on the mRNA for proper attachment. If the base change results in a different codon that still codes for the same amino acid, then a tRNA with the appropriate anti-codon can still attach. However, if the change alters the codon to encode a different amino acid, a different tRNA molecule with the corresponding anti-codon for the new codon would attach instead.
What is tRNA used during translation?
tRNA (transfer RNA) is used to bring the amino acids to the ribosome when a protein is being made. tRNA has an anticodon that matches with the codon on the mRNA, so that it knows which amino acid to add to the protein that is being created.
How is the placement of the amino acid during translation is determined by the?
During the translation process, the translation machinery reads the sequence of nucleotides present on the mRNA. The sequence of nucleotides on mRNA is divided in codons, these are set of three nucleotides. There are total 64 codons that contiguously present on mRNA. corresponding to each mRNA codon there is a tRNA that has an anticodon loop that has three nucleotide complementary to the codon. Now Anticodons bind to their specific amino acid called as the charging of the tRNA and carry to the mRNA that is bound to ribosome. The catalytic activity of the 16s rRNA leds to the formation of peptide bond between the coming and the already added amino acid.
Which amino acid will be carried to a RNA molecule containing the triplet code A-A-A?
A tRNA molecule with the anti-codon AAU should match up with the mRNA codon UUA. This tRNA will be carrying the amino acid Leucine.
How does a ribosome match an amino to a codon on the mRNA it is reading even though amino acids cannot directally base pair with nucleuic acids?
Ribosomes match amino acids to codons on mRNA through the use of transfer RNA (tRNA) molecules.

What part of tRNA should match the codon of the mRNA?
The anticodon loop of tRNA should match the codon of the mRNA during translation. The anticodon is a sequence of three nucleotides on tRNA that is complementary to the codon on mRNA, allowing for the correct amino acid to be brought to the ribosome during protein synthesis.
What is the significance of codon-anticodon pairing in the process of protein synthesis?
Codon-anticodon pairing is crucial in protein synthesis because it ensures that the correct amino acid is added to the growing protein chain. The codon on the mRNA molecule must match with the complementary anticodon on the tRNA molecule to bring the right amino acid. This accurate pairing is essential for the proper sequence of amino acids in the protein, which ultimately determines its structure and function.
What molecule is the anti-codon found on?
A nucleotide triplet in a tRNA molecule that aligns with a particular codon in mRNA under the influence of the ribosome, so that the amino acid carried by the tRNA is added to a growing protein chain.
Can you explain how to interpret a DNA to protein chart?
To interpret a DNA to protein chart, start by identifying the DNA sequence in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid. Use a genetic code chart to match each codon to its corresponding amino acid. Then, read the amino acids in order to determine the sequence of the protein that the DNA codes for.

What is the relationship between codons and anticodons?
A codon is found in the DNA sequence and in the mRNA sequence. The anticodon is the opposite sequence that would match with the sequence of the codon and allows pairing of the anticodon with the codon
What is 3 nucleotides on trna that match to a specific condon on mRNA?
The three nucleotides on tRNA that match to a specific codon on mRNA are called the anticodon. The anticodon base pairs with the codon on mRNA during protein synthesis, ensuring that the correct amino acid is brought to the ribosome. This matching process is crucial for accurate translation of the genetic code.

tRNA (transfer RNA) is used to bring the amino acids to the ribosome when a protein is being made. tRNA has an anticodon that matches with the codon on the mRNA, so that it knows which amino acid to add to the protein that is being created.
What identifies the specific amino acid for tRNA?
The messenger RNA strand. When the tRNA inserts itself between the two portions of the ribosome attached to the mRNA strand, the specific tRNA depends on the 3 nitrogen bases on the mRNA (the codon) that are about to be read. The tRNA that arrives has a corresponding "anticodon" to go with the codon on the mRNA. For example, if the nitrogen bases on the mRNA strand are adenine, guanine, and cytocine the tRNA will have an anticodon of uracil, cytocine and guanine. The tRNA that has the corresponding anticodon to the codon on the mRNA will bring with it a specific amino acid but it is the codon on the mRNA that ultimately decided which amino acid is next in line.
