Question

Quizplus · Accepted Answer

Translation of mRNA always occurs in the 5`→3` direction due to the directionality of ribosomes and the codon-anticodon pairing between the mRNA and tRNA. Therefore, option B is the correct choice. Option A is incorrect as mRNA translation is unidirectional. Option C is incorrect as it is the opposite direction of translation. Option D is also incorrect as option A and C are not correct. Option E is also incorrect as one answer choice must be correct.
