Question

Which of the following eukaryotic RNA polymerases is responsible for transcription of tRNA transcripts?

a. RNA pol I
b. RNA pol II
c. RNA pol III
d. RNA pol IV
e. RNA pol V

Answer 1

RNA pol III.

Step-by-step explanation:

Transcription may be defined as the process of formation of different RNA molecule from the complementary DNA template with the help of transcription factors and enzymes . Different RNA molecules like rRNA , mRNA and tRNA are produced by the transcription.

tRNA or transfer RNA is the important RNA molecule that bring the amino acid during the process of translation. RNA polymerase III enzyme is required for the transcription of tRNA. The RNA pol III is also involved in the transcription of 5S rRNA and other small RNA s. RNA polymerase III is the house keeping genes and express constitutively in almost all cells.

Thus, the correct answer is option (c).
