Answer:
The anticodon of a particular tRNA molecule is a. a complementary to the corresponding mRNA codon. Below, I let you an explanation of how DNA translation ocurrs as a complement to your study.
Explanation:
The translation of the genetic code is a process in which RNA becomes an amino acid junction to form a protein. This is a process which is divided into three parts: initiation, elongation and termination.
In the Initiation stage the ribosome binds with the mRNA and the first tRNA so that translation can begin.
Initiation :
For this process it is necessary to have:
• A ribosome (specialized organelle)
• An mRNA which carries the instructions
• A "start" tRNA that carries the first protein amino acid
When these three things come together, the initiation complex is formed, which will begin the formation of proteins. For this process it is necessary that the cell provides energy in the form of guanosine triphosphate (GTP )
Elongation occurs when the polypeptide chain increases in length.
In the ribosome there are several specialized places for each function. The first tRNA, which carries methionine, is located in the center of the ribosome space in a place called site P. Next to this site, a new codon is exposed, in another space and is called site A. Site A will be the location space for the next tRNA, whose codon is complementary to the codon that is exposed. This means that each tRNA is accompanied by auxiliary proteins, and only one tRNA that binds perfectly will be "released" at site A. To release the tRNA, a molecule that stores energy mentioned above, guanosine triphosphate (GTP) is used.
After the corresponding tRNA is located at site A, the formation of the peptide bond is given which is responsible for connecting one amino acid to another.
Termination occurs when a stop codon in the mRNA (UAA, UAG, or AGA) enters site A. Here release factors read the termination codons and are located at site P these release factors interfere with the function of the enzyme responsible for forming the peptide bonds then finally the tRNA chain is separated, and the newly dormant protein is released
