Which of the following statements about tRNA molecules is false?
(A) The enzyme that attaches an amino acid to a tRNA is aminoacyl-tRNA synthetase (B) Although composed of a single strand of RNA, each molecule contains several sho, double-helical regions (C) The amino acid attachment is always to 3' end of the molecule. (D) There is at least one tRNA for each of the 2 amino acids
(D) Answer-D. There is at least one tRNA for each of the 2 amino acids* There is at least one tRNA for each of the 2 amino acids RNA which transfer amino acid from the cytoplasm to the ribosomal protein synthesizing machinery* Clover leaf shape in the secondary structure.* L-shaped teiary structure, Single tRNA contains 74-95 nucleotides.* Cytoplasmic translation system Possess 31 tRNA species* Mitochondrial system Possess 22 tRNAs'Contain significant propoion of nucleosides with unusual bases.* Dihydro uridine (contain Dihydrouracil)* Pseudouridine* Inosine (contain Hypoxanthine)* Ribothymidine
