How are nucleic acids attached to trna
WebEach tRNA has its corresponding amino acid attached to its end. Where is tRNA found? tRNA or Transfer RNA Like rRNA, ... Transfer RNA, or tRNA, is a member of a nucleic acid family called ribonucleic acids. RNA molecules are comprised of nucleotides, which are small building blocks for both RNA and DNA. ... WebAmino acids are attached to the tRNA 3'-end as a prerequisite for entering the ribosome for protein synthesis. Amino acid attachment also gives tRNA access to nonribosomal cellular activities. However, the normal attachment is via an ester linkage between the carboxylic group of the amino acid and the 3'-hydroxyl of the terminal A76 ribose in tRNA.
