Choose one of the following Which of the following is the primary site of protein assembly within eukaryotic cells? Each tRNA has its corresponding amino acid attached to its end. When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.

Then the tRNAs and ribosome continue to decode the mRNA molecule until the entire sequence is translated into a protein.

An anticodon is the three-base sequence, paired with a specific amino acid, that a tRNA molecule brings to the corresponding codon of the mRNA during translation. The anticodon sequence is complementary to the mRNA, using base pairs in the anti-parallel direction.

Keep in mind that adenine binds to uracil in RNA. Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain.

A tRNA molecule will enter the ribosome bound to an amino acid. This amino acid is then added to the peptide chain by the ribosome.

It can then transfer its amino acid residue to the ribosome, where it is incorporated into the growing polypeptide chain. The tRNA molecule is the released from the ribosome and recycled. Amino acid sequence is determined by the sequence of codons on mRNA. Interactions between the codons on mRNA and the anticodons on tRNA are what allow the formation of the appropriate peptide bonds. Chaperones are later used to facilitate the development of protein structure, but are not involved in checking protein sequence.

If the enzyme, aminoacyl-tRNA synthetase malfunctions, which of the following processes will be impeded? During translation, tRNA molecules that are bound to specific amino acids are fed into the ribosome in a specific order that is complementary to the mRNA strand. Once a tRNA is used up, it loses its amino acid. As a result, it must interact with aminoacyl-tRNA synthetase before it can be used again in translation. A malfunction in aminoacyl-tRNA synthetase would result in a shortage of charged tRNA molecules and a decrease in translation processing.

Post-transcriptional modification is required for the mRNA to mature and exit the nucleus. The ribosome will then recruit tRNA molecules to the complex in order to synthesize the protein product. Each amino acid binds to a specific kind of tRNA. Then, the tRNA molecule containing the corresponding anticodon binds to the enzyme. The correct tRNA molecule is identified by aminoacyl-tRNA synthetase by its anticodon sequence and other areas of its structure.

Ribosomes are non-membranous organelles that direct protein synthesis by reading mRNA and joining amino acids into strands of polypeptides. Ribosomes exist in both free and membrane-bound states. They are synthesized in both the nucleolus and cytoplasm.

The components that make up these non-membranous organelles are rRNA molecules and a variety of proteins. Ribosomes have a large and a small subunit, together called the translational apparatus. The small ribosomal subunit reads the mRNA strand and the large ribosomal subunit joins amino acids into polypeptides.
