Great Question.

The triplet Codon, as represented by the sequence of Dna bases, would appear to be inverted into anti-Codon form in the mRna molecule.

This makes the triplet Codon on the transfer-Rna Codon form.

mRNA, or messenger-RNA, contains the codons used in the process of translating RNA into proteins. The tRNA, or transfer-RNA molecules, contain the anti-codon.

Each tRNA has an amino acid attached by an aminoacyl tRNA synthetase. The amino acid attached by this enzyme corresponds to the codon with which the anti-codon on the tRNA will pair. The anti-codon is the set of complementary base pairs to the codon; if the codon reads 5' AUG 3', the anti-codon will read 5' UAC 3'. (The amino acid that will attach to this specific tRNA is methionine, the amino acid that signals a start to translation and will thus begin every polypeptide chain translated.)

Which type of RNA contains codons?

Messenger RNA (mRNA). Transfer RNA (tRNA) contains anti-codons.


Which type of RNA contains the codon?

Messenger RNA, or mRNA contains the codons. tRNA (transfer RNA) contains the anti-codons which bond to the codons of the mRNA. Amino acids are attached to the tRNA and form polypeptides based on the codons on the mRNA.


What are codon and anticodons?

Codon = 3 amino acid sequence found on mRNA. Anti codon = 3 amino acid sequence found on tRNA.The codons are for the traslation of mRNa to an amino acid sequence by using ribosomes.


What is tRNA's function?

tRNAs are small RNA molecules that carry amino acids to growing polypeptide chains that are being made in a ribosome. The have anti-codons that are complimentary to the codons on the mRNA. They carry an amino acid that is specific to their anti-codon.


Where does the process of translation do in mRNA?

The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.

What is directly responsible for the sequence of amino acids in a protein?

The sequence of codons in mRNA, or messenger RNA, is most directly responsible for the sequence of amino acids in a protein. Each codon is comprised of 3 nucleotides.
