can someone explain the role of tRNa in protein synthesis?
tRNA's are specific. the are clover shaped structure. at the buttom they have Anticodon ( 3 bases) . the anticodon is specific to a certain amino acid. that amino acid itself will get attached to the tRNA (on the top). you could have 3 or several base sequence in the anticodon that goes with the same type of amino acid. After amino acids get attached to tRNA in the ribosome, the tRNA-Amino Acid complex will attach its anticodon to complimentary codon (complimentary bases) on the mRNA that is in the subunit of ribosome. two tRNAs at a time. while the two of them are getting attached to mRNA codons, polypeptide chains form between the amino acids. once its done, tRBA get$ deattached from the mRNA and the amino acid (it goes back to the large unit in ribosone to get attached to another amino acid) meanwhile another tRNA-aminoacid complex comes bext to the mRNA, codon attach to anticodon, polypeptide chains form between a.a and the tRNA leaves and the cycle continues until the line of mRNA is over and and you have a polypeptide chain formed (which is the base of protien structure).........
understood or ?? Good luck
