Which of the following accurately describes the process of translation?



A. Each codon calls for a specific nucleotide.
B. Each tRNA molecule has a codon that matches an mRNA anticodon.
C. The process continues until a ribosome reaches AUG.
D. The process continues until a ribosome reaches UAA, UAG, or UGA.





Respuesta :

The correct answer is C.
Translation is the second part of protein synthesis. In eukaryotic cells, this process takes place on the cell organelles called ribosomes that are located or found in the cell cytoplasm and in the endoplasmic reticulum.
Translation takes place in four stages namely activation, initiation, elongation and termination. Termination occurs when site A of the ribosome meets a stop codon which is either UAA, UAG or UGA. Since there is no tRNA that matches that codon, tRNA cannot connect to it. This stops the ribosome and the polypeptide breaks off the ribosome.
