All mature tRNAs have the sequence CCA at their 3’ end.(a) True(b) F

1.	All mature tRNAs have the sequence CCA at their 3’ end.(a) True(b) FalseI have been asked this question at a job interview.My query is from Gene Expression topic in portion Gene Expression of Cell Biology
Answer» The correct answer is (a) True For explanation I would say: All mature transfer RNA molecules have the CHARACTERISTIC trinucleotide SEQUENCE CCA at their 3’ end. This sequence is ENCODED in the tRNA gene in prokaryotes while it is added enzymatically in EUKARYOTES.
