The DNA sequence responsible for an mRNA codon is found in the coding region of a gene, specifically in the form of triplet base pairs. During transcription, RNA polymerase synthesizes mRNA by complementary pairing with the DNA template strand, where each group of three nucleotides (codon) in the mRNA corresponds to a specific amino acid or stop signal in protein synthesis. For example, if the DNA sequence is A-T-G, the corresponding mRNA codon would be U-A-C. Thus, the sequence of nucleotides in DNA directly determines the sequence of codons in mRNA.
What else can I help you with?
What tRNA molecule will match the mRNA codon produced from the following DNA code?
To determine the matching tRNA molecule for an mRNA codon derived from a given DNA sequence, first, transcribe the DNA to mRNA by replacing thymine (T) with uracil (U). Then, identify the corresponding codon from the mRNA. Each codon consists of three nucleotides, and the tRNA anticodon will be complementary to this codon. If you provide the specific DNA sequence, I can help you find the exact tRNA molecule.
If the codon on the DNA strand is CAG then the mRNA codon that will bind to it will be?
If the codon on the DNA strand is CAG, the corresponding mRNA codon will be GUC. This is because during transcription, adenine (A) pairs with uracil (U) in RNA instead of thymine (T), and cytosine (C) pairs with guanine (G). Thus, the DNA sequence CAG is transcribed to mRNA as GUC.
What is the amino acid sequence for a DNA strand with the base sequence DNA-AGGTAGAT?
Serine, Isoleucine. Last codon is incomplete.
Is the nucleotide sequence in an mRNA codon an exact copy of the DNA triplet that coded for it?
Yes, the mRNA sequence is created by transcribing the complementary strand of the DNA sequence, so it is almost an exact copy. However, in RNA, uracil replaces thymine, so the mRNA codon is identical to the DNA triplet except for the substitution of uracil for thymine.
What is a triplet of nucleotides that is the code for one amino acid?
I don't understand your question. mRNA does not have triplets. Did you mean codon? Triplet refers to DNA, codon to mRNA.
What tRNA molecule will match the mRNA codon produced from the following DNA code?

Then, identify the corresponding codon from the mRNA. Each codon consists of three nucleotides, and the tRNA anticodon will be complementary to this codon. If you provide the specific DNA sequence, I can help you find the exact tRNA molecule.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of amino acids in a protein is directly determined by the sequence of nucleotides in the gene that codes for that protein. This process occurs during protein synthesis, where the genetic information is transcribed from DNA to mRNA and then translated into a specific sequence of amino acids.
A codon is a triplet base sequence in?
DNA
What group of three nitrogenous bases in DNA or mRNA that code for one amino acid?
A codon in DNA or mRNA is a group of three nitrogenous bases that encode for one specific amino acid. The sequence of codons in the mRNA is read during translation to determine the amino acid sequence of a protein.
If the codon on the DNA strand is CAG then the mRNA codon that will bind to it will be?
If the codon on the DNA strand is CAG, the corresponding mRNA codon will be GUC. This is because during transcription, adenine (A) pairs with uracil (U) in RNA instead of thymine (T), and cytosine (C) pairs with guanine (G). Thus, the DNA sequence CAG is transcribed to mRNA as GUC.
Where do you find anticodon?
The anti-codon is the molecule of mRNA in the nucleus which copies the codon from DNA in reverse. This process is reversed again when tRNA copies the mRNA in reverse, thereby restoring the original codon sequence.
What is the amino acid sequence for a DNA strand with the base sequence DNA-AGGTAGAT?
Serine, Isoleucine. Last codon is incomplete.
Is the nucleotide sequence in an mRNA codon an exact copy of the DNA triplet that coded for it?
Yes, the mRNA sequence is created by transcribing the complementary strand of the DNA sequence, so it is almost an exact copy. However, in RNA, uracil replaces thymine, so the mRNA codon is identical to the DNA triplet except for the substitution of uracil for thymine.
What is a triplet of nucleotides that is the code for one amino acid?
I don't understand your question. mRNA does not have triplets. Did you mean codon? Triplet refers to DNA, codon to mRNA.
Why can't the mRNA base sequence ATC be a codon?
RNA uses Uracil (U) in place of Thymine (T). Thymine is exclusive to DNA.
What is the DNA sequence that represents the start codon?
The start codon is represented by the DNA sequence "ATG," which corresponds to the mRNA codon "AUG." This sequence signals the beginning of protein synthesis and codes for the amino acid methionine. In the genetic code, the presence of this start codon is essential for initiating translation in both prokaryotic and eukaryotic organisms.
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
