Each Trna Will Base Pair With Only One Codon

There are a total of 64 different codons and more than one codon translates into each amino acid. TRNA is only 70-90 nucleotides in length making it the smallest out of the three main RNAs mRNA and rRNA.

The stop codon is one of UAA UAG or UGA.

. F 5 C34 enables decoding not only of the AUG codon but also of the AUA codon as Met 66 Fig. A strand of mRNA obviously has multiple codons which provide the information for multiple amino acids. TRNA is encoded by DNA in the cell nucleus and transcribed with the help of RNA polymerase ΙΙΙ.

The modification 5-formylcytidine f 5 C is present at position 34 of mt-tRNA Met ref. Structure of Mature tRNA. The start codon in all mRNA molecules has the sequence AUG.

Each three-base word is called a codon and the series of codons holds the information for the production of the polypeptide chain. When a ribosome finishes reading an mRNA molecule the two subunits separate and are usually broken up but can be re-used. The molecular weight of the tRNA molecule ranges from 25000 to 30000 Dalton.

Since there are no tRNA molecules that recognize these codons the ribosome recognizes that translation is complete.
