What occurs In both prokaryotic and eukaryotic tRNA maturation?
A) The pre tRNA molecule is trimmed by exo and endonucleases
B) The pre tRNA is spliced
C) The mature tRNA is capped at the 5' end
D) There is extensive RNA editing

Question

Quizplus · Accepted Answer

In both prokaryotic and eukaryotic tRNA maturation, the pre tRNA molecule is trimmed by exo and endonucleases to remove any extra nucleotides present at the ends of the molecule. This process is crucial for the formation of a mature and functional tRNA molecule. However, the other options listed (B, C, and D) are not common to both prokaryotic and eukaryotic tRNA maturation. Eukaryotic tRNA molecules are capped at the 5' end, but prokaryotic tRNA molecules are not. Splicing occurs in some eukaryotic tRNA molecules that contain introns, but this does not occur in prokaryotic tRNA molecules. RNA editing is a rare process that occurs in some eukaryotic tRNA molecules, but it is not found in prokaryotic tRNA molecules.
